You could, but you wouldn't know if they disentangled in the meantime without communicating. Entanglement still doesn't allow information to travel faster than light. Part of the problem is that if they're at the same place to sync with each other, to then be at A and B they'll need to travel outside of an intertial reference frame causing time dilation for them.

Ah, ok, I see. To make meaningful use of the entanglement you'd have to bring the clocks back together (or communicate between them, but that's essentially the same -- there is frame-switching no matter what). But this is exactly the setting of the twin paradox [1] which is a more well-known example of trying to equivocate between events in distinct frames.
