More or less. Markers are hard coded in the parser. For example, *text*
is parsed as (bold (... some properties...) "text") without looking at
`org-emphasis-alist'.
Then, it's up to each exporter to produce something meaningful with
`bold', `italic' `underline', `strike-through', `code' and `verbatim'
markup. For a beamer back-end (which is not written yet), I'd suggest to
treat `bold' as "\\alert{%s}", for example.
Unfortunately, the parser assumes `org-emph-re' is a defconst. I'd like
to remove dependency on that variable anyway, but it's difficult to
create a perfect test. For example, the following one is a bit naive:
#+begin_src emacs-lisp
(and (save-excursion
(if (bolp) (looking-at "\\*\\w")
(backward-char)
(looking-at "\\W\\*\\w")))
(save-excursion
(re-search-forward "\\w\\*\\(\\W\\|$\\)" paragraph-limit t)))
#+end_src
