By definition not.

Light slowing down is nothing special - it slows down coming through
anything that isn't a vacuum.

(I believe the current record stands at 7m/s?)

Removing the last few particles, if any, isn't going to cause a sudden
jump in light speed. The figure we know for c is indeed that of light in
a vacuum.

Removing microwave radiation is nothing to do with the density.

The only way to do anything strange would be to have *negative* density.
For this, we would require some particles with negative mass. Such things
would be very useful - we could also use them for antigravity, and all
sorts of other tricks.
