This is a guess, but even if it's not registered I'm thinking ford would be able to detect the previous tune was from their own engineering.You're taking a gamble with those aftermarket tunes vs. your warranty. Ford could detect a tune was installed previously and deny based on something.
If you want to take that same gamble, just tune it with the PowerPack yourself (not registering it) and try to remove the tune if you have a problem, and have them prove that the "mystery tune" that was there before caused the problem.
Regardless..would a person with a transmission problem at 40k miles have rather had an aftermarket tune that wasn't related to the problem (or at least got the opportunity to have it proven that it was), or would they want the FRPP tune and already be out of warranty when the transmission died, whether the tune was at fault or not?
Personally, there isn't really anything that would make me consider contractually ditching 30k miles and two years off my factory warranty.
