Most definitely. In fact, you should delete the binaries for sed, awk, cc, gcc, grep, rm, ls, cat... well, just delete your /bin directory.
But seriously, of course you shouldn't. As with any job, you should use the appropriate tool for the task at hand. Just because a hammer will put screws into a piece of board, you probably don't want to do that.
While it's true that the answer to the question ``Can I do (some
arbitrary task) in Perl?'' is almost always ``yes'', that doesn't mean
this is necessarily a good thing to do. For many people, Perl serves
as a great replacement for shell programming. For a few people, it
also serves as a replacement for most of what they'd do in C. But for
some things, Perl just isn't the optimal choice.
