Sort of! My impression is that LISP is a little more powerful than what we're building up in the article. I wanted to focus on a few specific aspects (like first-class cross-environment imports and serializing continuations) but I'd ofc expect all of that to be expressible in LISP.
It's fun to theorize about an alternate universe where JavaScript has a LISP-like syntax (Brendan Eich originally wanted "Scheme in the browser"[1], so this isn't so far-fetched!). Indeed, `interpret` sounds like a LISP macro that can "partially evaluate" code (so someone else, ie. the browser can continue to evaluate it).
