Presumably something requires or required it.  Try
sudo apt-get autoremove
If that removes it then whatever it was that required it has been
removed (possibly distro-info was installed and then removed).

If not try
sudo apt-get remove -s distro-info-data
The -s says to simulate removing it but not actually do it.  You can
then see whether removing it forces the removal of anything else.  If
it just says it will remove that package then you can safely remove
it.
