I wouldn't bother doing the check first, I just change the code to:

$logger->error(sub {"Erroneous array: @super_long_array"});

then I believe it does not get expanded until inside Log::Log4perl when it decides to log or not.

So now all you need is a Perl Critic rule for using sub {} in logging ;-)
