Not directly I don't think.

The data is bytes, words, or whatnot.  The TreeView does its "row" drag
with a C pointer to the TreeModel in bytes followed by the row coords as
a string.  Not sure it does anything with the reference counting (does
the source widget look after that maybe?).

Of course it can only work within a single running process.  I think
there's some flags to drag_dest_find_target (hiding in Gtk2::Widget) to
check the same app or same widget (Gtk2::TargetList).
