The chance that you can port code without actually rewriting it is pretty slim. But then, people have been rewriting Lisp code to run in C++. If you want TCO in CL then use one of the dozen implementations which supports it. People btw. used to write some non-trivial code which ran in both Scheme and CL with the help of a Scheme on top CL, a compatibility layer or a translator. But that's now relatively rare.
