Can't think of a situation when that would be possible. I assume by uppers you mean the fork crown? On some forks there are screws there to remove the crown, not likely this one.
It is possible (though more work than it's worth) to remove the crown in the same manner I described.
If you mean the upper stanchions, than no. Because then you would have two usable forks... it's just a spring and elastomer in there.
