I am sure it is not limited to any specific number of moves. In fact, for the bonus question they don't ask you to send in the actual moves, just a solvable starting state. Once you know the conditions required for it to be solvable it's really easy (so they are really asking you to determine the conditions that make it solvable, or at least enough so that you can create at least one solvable state). They've credited me with the solving the bonus challenge and I didn't check to see how many moves it would take to solve it from either my initial solution or my much improved (as in smaller total amount added) solution.

I am trying to say that: they should have limited the number of moves, because it is really very easy to find a solution once the number of moves is unlimited, as it is already easy with limited number of moves.
