With the fuselage plugs forward of the wing, would this mean the engines are closer to CG, therefore no need for MCAS?
The MAX 10 fuselage is also lengthened behind the wing:
In October 2016, Boeing's board of directors granted authority to offer the stretched variant with two extra fuselage sections forward and aft with a 3,100 nautical miles (3,600 mi; 5,700 km) range reduced from 3,300 nautical miles (3,800 mi; 6,100 km) of the -9.
Basically the center of gravity of MAX 7,8,9 and 10 is in the same location (range) in respect to the wing, or mean aerodynamic chord (MAC) of the wing to be more precise. As the engines are essentially the same in all MAX variants, and so is the location of them, the engine location from CoG is pretty much precisely the same.
The need for MCAS cannot be solely determined by CoG of MAX 10, as the longer fuselage may have some other effect on stability, but my personal guess is, some kind of maneuvering augmentation is necessary.
