Igor, I believe Lightroom relies on lens definitions stored in small XML files rather than an internal database. Adobe has a freeware tool for creating your own lens profiles with distortion settings and all, but I guess that's a solution overshooting your problem complexity. However I think you may achieve what you want by tinkering with the XML file that Lightroom wants to use for your lens.
The lens definition files resides in the folder <systemdrive>:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0\<brandname>\ They have extension *.lcp. Open the file for the Tokina in your favourite text editor, and replace all occurrences of the lens name with the name you want. The downside is of course that you also assign data for chromatic aberrations and lens distortions that may not match your lens. So you should probably turn off "Use profile corrections" in the develop module. One more caveat; I have never actually tried this myself... :-) Hope it works, I wouldn't hesitate to try if I had the problem myself, at least.
