On further reflection, this isn't as badly wrong as I thought (though  
it still seems confusing). You'll actually get the same error message  
if you use an AAT or OT font as follows:

   \font\x="Hoefler Text" at 10pt \x
   \hbox{\XeTeXcharglyph`g}

because \XeTeXcharglyph is in effect a read-only numeric value, not  
an actual printable "thing" that you can put into a box. If you  
wanted to put the glyph number in the box, you should say:

   \hbox{\number\XeTeXcharglyph`g}

and if you want to print the glyph, you say (as in the original  
example):

   \hbox{\XeTeXglyph\XeTeXcharglyph`g}

But as \XeTeXglyph was ignored as invalid in TFM fonts, you're left  
trying to use \XeTeXcharglyph as part of a horizontal list rather  
than as a numeric value, and hence the (somewhat surprising) error  
message.
