Yes, one just needs to derive a class from DataOut and then overload the 
first_cell/next_cell() functions to iterate over (now possibly inactive) 
cells that do not exceed a certain refinement level. This may not work 
on parallel triangulations, though, unless you make sure that all 
children of that cell are locally owned.
