TDB union graph without ARQ

If I just ask a TDB dataset for the named graph of the union graph,
can I then use the usual Jena API to get iterators?

Yes - you have to ask for it by URI.

What you can't do is have the default graph the union graph in the Jena 
API (only query) because that does not work for updates.  In the API, 
the default graph is always the storage default graph.  In SPARQL 
update, union graph processing is not applied to the template (the changes).
