Just scrounged a pair of MTB wheels - but they have QD spindles.

My locking up chain isn't long enough to go through both wheels, the
frame and whatever I'm chaining it to.

Is there any technical reason why I couldn't swap the spindles over from
a pair of old damaged wheels?

I'd normally call them axles.

For a traditional wheel, provided they're long enough, the threads match
the cones, and the axle isn't knackered, it'll work.
