Not at present.  Brett Schwarz recently mentioned on c.l.t. that he
had some code to do this (Brett?  Is this publically available?),
but Tile doesn't support it out-of-the-box right now.

I don't have any immediate plans to add it, either, but here's
how I see it working: first, a general-purpose "edit-in-place"
utility that would create an entry widget, [place] it in
an existing widget at a programmer-specified location, and
eventually pass the edited value to a user-supplied callback
(on <KeyPress-Return>, <FocusOut>, etc.)  Second, the ttk::treeview
will need a [$tv bbox $item $column] method, to figure out where
to place the entry widget.  And third, a new utility procedure like
[ttk::treeview::editCell $tv $item $cell] that would glue the first
two pieces together.  (This should probably have a callback option
too; not sure yet.)  The application programmer can call this
routine from widget bindings as appropriate for the application

If there's a one-size-fits-all solution that works for all use
cases, this might be promoted to a treeview widget instance method
like the BWidget Tree widget has, but probably not.
