Not in the Classic or NG. To engage the autopilot you need to release elevator pressure on the stick, otherwise it will not engage. So if you are pulling against an MCAS-inspired nose down trim, you cannot engage the autopilot. (MCAS gives 10 seconds or 2 degrees worth ofnose down trim for each input - which is a heIIava lot of trim input - and then just while you are wondering what is going on, it gives you another 10 seconds of nose-down trim.)
