As Sebastien suggests, if you can identify export status depending on
tags you can do it with a filter.
Here's an example that's perhaps a bit too verbose and not thoroughly
tested:
#+BEGIN_SRC Org
#+TITLE: Conditional export
#+options: tags:nil
* Common intro
txt
** Pdf heading :latex:
the math is really pretty!
** HTML heading :html:
the text features hyperlinks!
** More common notes
Intro over
* Code :noexport:
#+begin_src emacs-lisp
(defun rasmus/conditional-export (settings backend)
"Change SETTINGS to include dynamically set export-tags.
Enable the use of BACKEND as EXPORT_TAGS. A derived backend is
treated as its parent."
(let ((backends (remove-duplicates
(mapcar (lambda (x)
(or (org-export-backend-parent x)
(org-export-backend-name x)))
org-export--registered-backends)))
;; for treating derived backend and parent backends differently:
;; (backend-or-parent backend)
(backend-or-parent (dolist (b org-export--registered-backends return)
(when (eq (org-export-backend-name b) backend)
(return (or (org-export-backend-parent b)
(org-export-backend-name b)))))))
(plist-put
settings :exclude-tags
(append (plist-get settings :exclude-tags)
(mapcar 'symbol-name
(remove backend-or-parent backends))))))
(add-to-list 'org-export-filter-options-functions 'rasmus/conditional-export)
#+end_src
#+END_SRC

Enough with the bla bla!
