Not to my knowledge. Apparently, according to https://www.emacswiki.org/emacs/NoThreading https://www.emacswiki.org/emacs/NoThreading, dynamic scope makes it devilishly difficult to implement os-level threading. It is, apparently, possible to automatically translate elisp into a lexically scoped lisp dialect, and rebuilt emacs on that foundation, but, again, to my knowledge, nobody's done that. And, there are occasional mutterings about making a new, natively multithreaded emacs, but nothing's ever made it into the GNU emacs repo, AFAIK. It does have process-based concurrency, which is basically where you spawn off a whole new emacs, then run your code within that. I've never used it, so I don't know how it works, other than the obvious disadvantage of having a large startup time and potentially memory use to start up another instance of emacs.
