I don't understand your question.
If you mean "Can the string '<object/>' be treated as an empty element
tag", the answer is no.
If you mean "Can the string '<object>' be treated as an empty element tag
if there is no matching '</object>'" then the answer is no according to
the current spec, and will probably remain "no" lest legacy compatibility
problems are discovered that require that to change.
If you mean "Can the string '<object></object>' be treated as an empty
element" then yes, what else would it be treated as?

Just like with <img alt="">, the lack of fallback content on either of
these would merely indicate that they were semantically neutral and not
conveying any extra information. For example:
<p>The foobar is a green circle.</p>
There is no fallback here because it would be redundant -- the image
paragraph is merely repeating the previous paragraph for emphasis in
