Definitely. The practical dynamic range is considered to be 
(full-well-capacity)/(noise). Or rather, that figure expressed in 
decibels, but you know what I mean.

The problem is that you can't really "remove the noise" in an image 
processor or image processing stage. You can remove image artifacts that 
are assumed to be caused by noise, but you have no way of knowing if the 
assumptions are right, since noise is essentially random variation added 
to the data. If, on the other hand, you can prevent the noise from 
entering the system...
