I wouldn't think so. My personal theory is AoA is sending valid data to one of the flight computers, that flight computer is sending invalid data to the MCAS, or the MCAS has a software problem. I suspect AoA is sending signed data, computer expects unsigned data, or possibly LSB/MSB conversion problem. Or it could just be faulty logic somewhere.

The sensors on Lion Air were 10+ degrees out of calibratiom IIRC. Critical AoA is somewhere in the realm of 17 to 20 degrees. That doesn't leave much room for where MCAS wouldn't be a problem. Also, AoA sensors are not normally safety critical. The MAX is the first 737 airframe for which this is the case.
