Could be, it's definitely a feature, as opposed to a processing artifact, as it's in the original image here:

Looks like a crater to me, a truly massive one if it is!
Luckily it's not long until we find out for sure
EDIT: this is from that post on UMSF:
"The feature near the limb at upper right is particularly interesting. Inspection of the original JPGs reveals that it is real. Looking closely at the diagram shows that the terminator is at upper left, i.e. the sun illuminates Pluto from lower right. This rules out shadows associated with a crater and makes this feature likely to be due to albedo variations."
