Yes, it's the aerodynamic lift from the big engine fans that was the 737 Max issue, according to Aviation Week. Fans have gotten bigger as engines have improved and the bypass ratios and fuel efficiency has gotten better. Think of the engines as a big horizontal stabilizer but it's at the front, in front of the center of gravity. Normally it doesn't do much anything since the angle of attack is zero. But if you increase pitch, it will increase nose-up momentum. For some reasons it's not common to put the engines further back. DC-9 style, on the sides of the rear fuselage might work. Or maybe over the wing and slightly to the rear, like Hondajet.
