Not in principle, just a matter of time.

There seem to be conflicts between hb-buffer.h in the new harfbuzz and 
harfbuzz-buffer.h in the old. e.g. hb_buffer_clear and 
hb_buffer_add_glyph. There may be other places, but that's what the 
compiler tells me to start with. I'm not sure how likely this is to 
cause problems if an application links to say a pango using hbng and the 
old hb in some other way. Visibility compiler options probably prevent 
it being a problem in cases like say QT.
