Fundamentally, yes

You unlink things using IUpdate.deleteObject(). In Beta-2.3 this is  
pseudo-manual process (ie. you must know what you want to delete and  
the order in which to delete it), leading up to Beta-3.0, and will be  
complete for Beta-3.0, is work on a delete service which will hide  
the majority of this from the programmer. You can look at the initial  
implementation here:

http://trac.openmicroscopy.org.uk/omero/browser/trunk/components/ 
server/src/ome/services/delete/DeleteBean.java

this should give you a good idea about how to do this from your own  
software.

Deleting "orphaned" binary data is done through the IRepositoryInfo  
service's "removeUnusedFiles()" method.
