Nick,
No... for the manual they've just hatched the limits for a couple of example CGs inside the existing overall limits.
It's the M=1.56 limit that's related to CG, the Mmo=2.04 boundary is purely certification-related.
I think the CG "corridor" is already posted, if not I'll do so.

It's more the other way around... the aft CG limit is 59% for anything above about Mach 1.5.
