In terms of single cycle waveforms specifically, no, not really. The Digipro machines can do things like interpolate between different waveforms or scan through the wave table, or stack four different notes of the same wave to create chords. Plus things like the delay per track, three LFOs per track, and FX machines all factor into your thinking when making sounds. Some degree of that is available to the DT but not all that much of it.
I shouldn’t think there’s much the DN couldn’t do in FM that the MM can, but the DN seems to be quite a smooth and clean sounding instrument in general, whereas the MM FM+ machines get you into nasty / percussive stuff very quickly. Also there is maybe more LFO control on the MM.
