Yes it can -- this is exactly what XeTeX does with OpenType families  
that have optical sizing information.

   \font\x = "Garamond Premier Pro" at 7pt
     % uses Garamond Premier Pro Caption

   \font\y = "Garamond Premier Pro" at 12pt
     % uses Garamond Premier Pro

   \font\z = "Garamond Premier Pro" at 18pt
     % uses Garamond Premier Pro Subhead

This happens automatically for installed font families that have the  
OpenType optical size feature. It can of course be overridden (with  
the /S=.... modifier on the font name).

It does not happen for fonts accessed directly by filename (or  
"external location") rather than real font name; if you ask for a  
specific file, you get that file.
