Yes and no.
No, in that digikam does not provide a way to limit the list of proposed 
lenses. That would be a nice addition (settings dialog where you can select 
the lenses you use from the full list, and digikam then only presents the 
lenses that fit e.g. focal length and are in your selection).

Yes, in the sense that you can edit the database outside digikam.
The lens database is provided by lensfun, which uses xml files to store the
data about all the lenses it knows about. You can edit those xml files and 
strip out everything you don't want (but the files might get overwritten at the 
next update). Hard to give more details without knowing what OS you use.
