would a fork from a 15" bike fit on a 17" or 18" bike?

yes and no. Depends on headtube length on both and the steer tube length on the fork

You will need to know the headtube size for both and the steerer length. I would assume they are similar so it will likely work, but I would measure to be sure

You would probably get problems with geometry and stability but it might work.
Try and post us what happened.

Almost surely not. The headtube of the larger bike is likely to be a couple of inches longer. The steerer tube has to match that so it will probably be too short.

The actual length of the fork "tines" could be different. If they are shorter, that would effectively increases the head-tube angle it would seem. That would make the bike have less straight-line stability or turn more quickly if the rake of the shorter fork is not greater and sufficiently greater to off-set the affect.

I know my bike, an Airborne Carpe Diem, uses an extra long cyclocross fork. Some folks who put on a non-Airborne "approved for the Carpe Diem" forks have complained that the CD is too twitchy. It actually has good straight line stability and can easily be ridden "no-hands".

For 'tines', substitute 'stanchions' :).

For 'tines', substitute 'stanchions' :).I'll take legs for $100.

I kinda like "tines" in the context of a fork:

tine (tīn)
n.

1. A branch of a deer's antlers.
2. A prong on an implement such as a fork or pitchfork.
--------
stan·chion (stănchən, -shən)
n.

1. An upright pole, post, or support.
2. A framework consisting of two or more vertical bars, used to secure cattle in a stall or at a feed trough.

Prong is good too.
