It can once it has been input.  The drumStyleTable tells LilyPond how to
typeset drum notes once they are in the music.  It doesn't tell LilyPond
what drum notes are permitted in music.  So you need to use the existing
names, or amend the parser.

Amending the parser is done with

drumPitchNames.slap = #'slap

Note that you can define multiple names for the same definition in the
drum style table, so you can also add

drumPitchNames.sl = #'slap

and this will work without further changes to mydrums.
