Entirely possible. The DOS executable is built with Watcom C, and there's what appears to be a Watcom specific ASM module included in the source for DOS builds. It's the CRT unit, so I assume it's where DOS screen size is set. I have to look at it and see what it does.

As mentioned upthread, G behaves as desired in an NTVDM session under XP, so NTVDFM is doing something vDOS isn't.
