Yes it can. The <b> by itself, without CSS rules, suggests (hints)
"boldface". A <b> element should be boldface even in a non-CSS-
enabled graphical browser such as NS 3. Therefore it is a non-CSS
presentational hint. Whether the /implementation/ that acts on
this hint uses CSS syntax or not is irrelevant.

http://www.w3.org/TR/html401/present/graphics.html#edef-CENTER :
   | The CENTER element is exactly equivalent to specifying the
   | DIV element with the align attribute set to "center". 

If <center> and <div align=center> are exactly equal, exactly why
don't they behave the same way?

If the purpose of a workable standard is interoperability and if under
your defintion any implementation can pick and choose what it determines
to be a "non-CSS presentational hint", then the results are not workable.
