Yes, to my understanding the only issue a pilot would run into with MCAS disabled and neutral is decreasing control forces at high angles of attack. The FAA requires control forces to monotonically increase with angle. I say "only" but that probably makes for a very weird feeling airplane to fly; how dangerous that actually is for a trained pilot I can't answer for sure but my gut and experience tells me not very.
