Yes!  For example, \emph{} has order 2 effect in LaTeX.

_<em>_ and *<strong>* are usefully different inside xterms (or vt100s)
with user agents such as "lynx" or "w3m".  In my opinion <em> should
be understood to have order 2 meaning at the level of content, while
<strong> should not be a legal child of <strong>.  Because such
content exclusions are not possible in XML DTDs, I think that the
XHTML specification should characterize <strong> at the content level
as idempotent.

(Alas, I don't know any present UA that handles <em> as having order 2
without the intervention of CSS.)
