Yes, but note that this may not be very portable:

use Config;

my @names = split ' ', $Config{sig_name};
print grep /WINCH/, @names;

This does not print anything on Windows, but gives me results on cygwin and Linux(Slackware). To OP: As always, read the documentation (man 7 signal). This SO post may also shed some light on SIGWINCH for Windows OSes.
