You can declare lexical-binding in the source block, like this:
#+BEGIN_SRC emacs-lisp :lexical t :tangle elisp.el
;;; elisp.el -*- lexical-binding: t; -*-
(defun lex-p ()
"Return t if lexical binding is in effect."
(interactive)
(let (lex
_lex-p)
(let ((lex t))
(setq _lex-p
(lambda ()
lex)))
(if (funcall _lex-p)
(message "lexical binding")
(message "no lexical binding"))))
(lex-p)
#+END_SRC
#+RESULTS:
: lexical binding
