I don't think so.

If the bombs had a "build-in" trigger, then both of them would have exploded for sure. If Jackal was honest about blowing up only one, if Lucy decided, it would mean he had to trigger the explosion consciously somehow and the ten seconds were just for putting more preassure on Lucy.
