Not really.
I wrote elisp.lisp
(http://clocc.hg.sourceforge.net/hgweb/clocc/clocc/raw-file/tip/src/cllib/elisp.lisp)
years ago to run ELisp code (that uses dynamic bindings)
under Common Lisp (that uses lexical bindings).
(The gist is to explicitly `declare` all variables `special`).
So, at the very least those old emacs lisp programs will still be
usable under CL.
