It would not surprise me if they redesigned the case to allow higher pressures. They might have monkeyed with the taper and overall length as well.
Bill Alexander had said that the Grendel was designed around the existing AR15's bolt size and magazine well. If I recall correctly, he said that the max design pressure for the case was 58,000 psi. If the case were designed for a significantly higher pressure, the walls and base would need to be thicker, reducing case capacity and increasing material cost.
I don't know what the guts of the M17 look like, but it would not surprise me if it could handle longer cartridges and/or higher pressures.
