Sure, but it is not Mathematica's InputForm:

https://reference.wolfram.com/language/ref/InputForm.html

The majority of code is written not in FullForm. In Lisp 100% of the code is written in s-expressions.

Typical Lisp and Lisp dialects all can be compiled: Common Lisp, Emacs Lisp, ISLisp, Scheme, Racket, ...

Which Lisps can not be compiled?

Do you really know what you're talking about here?

That's not a compiler...

I don't claim to be an expert on lisp, so further googling I find

https://racket.discourse.group/t/chez-for-architectures-with...

which has some discussion about this and that native backend.

Suffice it to say I am not any more confident that being compilable is somehow intrinsic to lisp.

From the Racket documentation:

https://docs.racket-lang.org/reference/compiler.html

"18.7.1.2 CS Compilation Modes

The CS implementation of Racket supports several compilation modes: machine code, machine-independent, interpreted, and JIT. Machine code is the primary mode, and the machine-independent mode is the same as for BC."

CS is the new implementation of Racket on top of the Chez Scheme runtime. Chez Scheme is known for its excellent machine code compiler.

Read above.
