As far as I know, if you only add a photo to Lightrooms catalog (not copying it), you can then only remove it from the catalog, not the catalog AND disk.
Solving your current problem might be difficult since now you have a bunch of photos sitting on your hard disk that is not found in any library. You can export Lightroom catalogs with the files, and hopefully it would also copy files that are only linked. Perhaps you could use this feature to export your current catalog (which exports a folder containing a Lightroom catalog and a folder hierarchy of photos), delete where you have your photos sorted now, and then use the exported library as your new Lightroom catalog. This should eliminate all those photos no longer contained in your library, but also will require a massive amount of drive space to store the new library before you can delete the old one.
Out of curiosity, what are your motivations for wanting to use both Lightroom and Aperture?
