Yes, but I wouldn't do that; being in ns doesn't mean it is stable. What I would propose to do is to have a strict copy of the rdfa default context entries in json ld (which is indeed a subset of tge one in csvw).

Can a context file refer to another one? Because then we could exchange the list of prefixes from the csvw context in favour of the separate one.
