If you're instructed to unlock the phone with your finger, and your "duress fingerprint" unlocks fake data, then you're misrepresenting that fake data as the real data and would presumably be considered to be making a false statement (though this is just speculation on my part). On the other hand, a "duress fingerprint" that locks out TouchID wouldn't be misrepresenting anything. But it wouldn't surprise me if they could still get you in trouble some other way for knowingly locking out the device after it's been confiscated.
