Yes. The Fatal Push will be deprived of its only target and fizzle. Note that ninjutsu does not target, and returning the creature is a cost and thus cannot be responded to.
Do note that this is dependent on when your opponent actually tries to destroy it. If they try to destroy it in the Declare Attackers Step, it is not yet an unblocked attacker. Only if they wait until the Declare Blockers Step can you do what you want.
