perl does not "register" what is installed so there could be no reliable way to do this,

when I am concerned that a machine does not have a module that I need I check for that module

If you installed them by usual means (ppm, CPAN, etc.) then they are indeed registered, and it is reliable.

As I said, PPM does keep an installed registry, and most people using Windows have ActivePerl and PPM

ppm query *

Or without that, these list, respectively, the modules that came with the Perl distro, and the modules you have added via CPAN or other standard means.

perldoc perlmodlib
perldoc perllocal
