Yes.  There are many layers in CEDET, and you can hook in external tools 
at whichever layer makes the most sense.  You could use an external 
parser like clang to produce tag lists, or as a back-end to look up 
symbols, or just use it for smart completion.  There are drawbacks if 
said tool is only used for smart completion, since other utilities such 
as tag navigation or decoration would still need a tagging parser.

It is generally handy to have an Emacs native parser for when external 
tools aren't available or only used for higher level functionality, but 
it is not necessary.
