Not really. The encryption key is generated by some PBKDF iterations over the PIN + a device-specific 256-bit key that's burned into secure storage. Unless they can get the latter from secure storage--which is probably fairly hard--this devolves into brute-forcing a random 256-bit AES key, which is not really feasible.
