Yes that's possible.
I downloaded it with Adobe Lensprofile Downloader
In LR ,I can choose it under Custom.
I have Panasonic Lumix G 20mm -F 1.7 ASPH on Panasonic GF1
and the available profile is (same lens) for Panasonic Lumix DMC-G3.
Thank you very much for the info!
You can find this statement:
Regarding lens vs camera+lens combinations. Generally, Adobe only supplies 1 profile per lens. Differences between cameras (e.g., crop factors) are automatically taken into account when applying the profile
