Of course, if one is hellbent on using grep for this, Perl will oblige with WTDIs galore...

One such solution:

perl -e 'print grep { s/param=// } @{[ "param=value" ]};'

...but this hardly qualifies as an argument in favor of using grep here

Agreed. Other than as a proof-of-concept, don't do this. I'd personally use map for the OPs exact stated desire. I suspect, though, if the OP gave the larger context of the problem, better solutions might be apparent.
