If the freezer doesn't shrink the battery I might try this approach,
though I think I'd prefer Paul's idea re gluing a handle to the battery.
The problem with that approach is that the battery surface is small and
a miscalculation on the amount of glue would probably just glue it in place.
I can see setting up a piece of plexiglass between my face and the
battery - mounting the plexi with plastic spring clamps that could
easily be mounted onto a tripod. Heavy leather leather gloves for my
hands and maybe a couple wet towels on my arms while doing the drilling
and inserting screws might cover things.
Only concern is with the battery exploding. You mention that the battery
might explode if not vented - given that the battery is enclosed on 5
sides by the Q's battery compartment, I assume there is a chance of it
exploding with the exposed side (what I would be drilling into) being
the vector for the blast. That does not sound appealing.
I'll think about it. I watched some videos of people blowing up lithium
batteries and was surprised at how forceful they can be. But these were
folks dropping the batteries in front of blow torches. But buying a
replacement camera for $150 or just selling off my lenses and exiting
the system may be better options.
I hope it just shrinks in the cold overnight.

Ouch, you're between a rock and a hard place there. If it was me I
would take the brutal approach, the battery is toast so I would opt to
destroy the battery however there is a danger to it. If you open the
battery and it gets sufficient oxygen even if discharged it can
spontaneously combust (burn, not generally explode if there is a
vent).
I would take it outside and bring a drill, electric screw driver, a
screw with good deep thread, a pair of robust pliers and a drill bit
slightly smaller than the screw. Drill into the battery, quickly screw
the screw in and yank the lot out. Otherwise send it in for service
(where they would very likely do exactly the same thing).

Thanks, Paul - sounds like it might work.

You might be able to attach a handle of sorts with two/part epoxy. I would
rough up the battery surface a bit first.

Jostein's post motivated me to pull out my Pentax Q, which has been
sitting in the bag for some time. The third party battery that is installed
in it appears to have swollen and is stuck tight. Anybody know any tricks to
removing a swollen battery?
The battery is pressed very firmly against the sides of the chamber but
has a label that wraps around the two large sides and the back. I was able
to get a needle under the label so I have something that will let me pull on
it, but it seems to be wedged in tight and the label is not so strong. Here
is a photo of the battery with needle under the label:

I can tied some fishing line around each end of the needle to get a
straight pull on the battery - its a little difficult to get leverage while
holding the latch in the open position.
Given how tightly its stuck I'm wondering if there is a way to get it to
shrink, at least temporarily. I stuck it in the freezer for an hour or so
hoping it would shrink, but so far no luck. I'll leave it in there
overnight. From what I read people freeze laptop batteries on the belief
that it gives them new life (learn something every day) and it sounds like
freezing the battery is safe. But otherwise litihium batteries require some
caution, so sinking a small screw into it to get enough leverage to pull it
out is not an option.
A used body would probably cost less than a repair, so going to the shop
is not an option.
Any suggestions?
