I doubt it. Grain is most apparent in even tones, like sky areas. With
digital sensors adjacent sensors will have the same readings so it's
reasonable to assume that the gap has the same information. With film,
and the differences from spot to spot (the area to sample has to be
decided upon) it would make it necessary to determine what is noise and
what is real data. For digital you need little more than a low pass
filter to smooth over the gaps. To deal with film grain sophisticated
processing has to be done to remove the dye cloud effects. It comes down
to the difference between simple filtering and real noise reduction.

This was what I was wondering about.
My next question is: If the same or similar interpolations to reduce the
noise from the distance between pixels in a digital camera were used to
reduce the grain noise in a scan from film, would this tend to level the
playing field?
