Quite a different issue compared to UAS...
From my own experience on the NG a wrong AoA input will result in UAS, unreliable altitude, vertical speed, wind information and ground speed display. It is a basic correction factor into the ADIRU that does effect all resulting air data related information and surprisingly the non air data related information of ground speed as well. It might be different in the MAX, but somehow i doubt it. As different airflow over the fuselage results in huge position error values for static and pitot tube values, the AoA vane corrects those very different position errors, therefore a wrong AoA indication will result in a completely unreliable air data set.
