Yes, you can safely remove Firefox installation (setup) files from older Firefox versions that you no longer have installed.
If you mean entries in the Control Panel Programs then you should be cautious because entries from older Firefox installation are usually leftover, orphaned, entries that all point to the current release and uninstalling such an older version will remove the current Firefox version.
