Yes: the distinction between pitching force from engine thrust, and pitching force from engine nacelle aerodynamic lift, is essential and, here, frequently elided.
MAX has more powerful engines with center of thrust lower than in NG, and they are both physically bigger and mounted such as to exaggerate an already increased aerodynamic pitching force.
The distinction is frequently neglected in discussion here. Both effects contribute to MAX's different handling characteristics, but differently in different flight regimes.
The result is that it is tricky to make a MAX fly like an NG, particularly while trying to conceal the system used to do it.
