Since macros can be set to expand to arbitrary elisp, I would think this
*should* be possible.  I forget the syntax but something like:

#+MACRO: efn (eval (get-export-file-name))

#+BEGIN_SRC emacs-lisp
(defun get-export-file-name ()
 (org-element-property :export-file-name (org-element--current-element) ))
#+END_SRC

* some heading
:PROPERTIES
:EXPORT_FILE_NAME: test-me
:END:

will get you somewhat close.  I don't understand the org-element api very
well though and it generally takes me a few tries to get this sort of thing
right.

3. Is it possible to create a file link which uses macro? I would like to

I don't think a macro will do this for you since, if I understand
correctly, macros are not aware of the export target.  So probably you
would need some other mechanism to od this.
