Yes, if you can feed power to it.
I don't understand all the innuendo about what works when some numbers
can put things into perspective.
Here are some EZNEC numbers. A 33' (1/2 wave on 20) wire on 20M with
one end at 2' and the other at 25'
Feedpoint % from end Z SWR
1.2 2445-9196j >100
6 746 -919j 39
11 301 -342j 14
15 230 -175j 7
This strongly indicates that some counterpoise of about 10% above the
ground (remainder of 33' in air) should be used to bring the Z down to
reasonable values for matching. Regardless, there will be a large
complex value of Z to null out.

Brian,
I repeat what I have posted several times:
A resonant dipole radiates the same no matter where it is fed - center,
end or anywhere in between makes no difference in the radiation pattern.
In other words, a dipole is a dipole, is a dipole.
The dipole refers to the current/voltage distribution, and not to how it
is fed.

Hi John,
This is great! Thank you for taking the time to write this.
Having only experimented with centre fed dipoles as base antennas over
the years these end feds open up a whole new set of placement
possibilities for me. I have to confess prior to this I thought of
(random wire) end feds as non resonant compromise antennas. Yet
another shattered paradigm for me.
Come spring I will in fact be trying these out in place of my current
dipole. I'll source and order the torriod cores now and I will surely
keep you posted. Also I think a 160m end fed will be a worthy project
this summer.
So height above ground of the end feds will have the same effect on
take off angle as it does with dipoles?
