If they are both very high quality, multi-coated filters, should work fine. In fact, it's a common technique to do so, when the ND filter alone isn't quite strong enough... Or when wanting both to reduce light (ND) and cut some reflections or glare (C-Pol) in a scene. ND filter alone can't do that. OTOH, there are times when you don't want to reduce reflections because they are an important part of the image', so will want to avoid a C-Pol.
Test on your lens to see if you have problems with vignetting when the filters are stacked.

Contrary to an earlier response, there's no problem adjusting a C-Pol when it's stacked with another filter.
