trim has nothing to do with the movement limits on control surfaces.

Stealth,

This is not universally true. On the Douglas DC-6, for instance,
elevator "up" travel is limited by the elevator trim position. Dialing
in the last 5 degrees of nose up trim allows an extra 3 degrees of
elevator "up" travel. This was done to limit elevator "up" movement
with aft CG loading conditions.

Happy Flying!
