Well, the Yamaha FM implementation isn't realy FM it's Phase Modulation and Phase 
Distortion is basicly Phase Modulation too. The best guess is that Casio uses a 
sine shaper as carrier since the function fits perfectly to the description Casio 
gives in the  CZ-Series manuals. 
A sine shaper is basicly a special version of an FM Carrier tuned down to 0Hz 
(FS1R, TG77 and various FM softsynths can do that) but Casio probably haven't 
used a sine as modulator but something what is able to do some waveform symmetry 
stuff, maybe comparable to the G2 shape oscillator, it at least sound pretty 
similar when using it at a Phase Oscillator tuned down to 0Hz...

Not exactly, since simulating one log/exp stage of an analog envelope needs more 
than one linear CZ stage...

...Summa
