In MIMO, Dis-similar Cable length to the dual pol feeds CAN be a problem.
Both cables should be the exact same length, or as close as you can make them.
This should not be a problem for a 10ft cable. Simply crimp the indoor
connector first, since ends terminated really close to each other.

10ft in RF cable is a Bad Idea I would put you board in a weather proof
box and put it next to your antennas

Why is 10' of cable a bad idea.
I am not doing MIMO, but I have cables from 8 to 145' working just fine.
And, the real question wasn't about using cables, but do they need to be
the same length.
Since MIMO is looking for the best signal and/or combining what is sees

I'm aware of cable loss issues, but in this case, that's just not an
option. LMR-400 has low enough loss at 5 ghz that I don't see any big
issue with using it, and the run really isn't all that long.
The radio system is an ALIX mini-itx
