You can, as long as your windows DCs are not newer than 2008 R2.  I think 
the only real caveat is with sysvol replication.  DRS replication is not 
supported, so you'll have to use rsync or similar.  See the Sysvol section

You may need a fairly recent version of Samba for this.  I believe RODC 
support is somewhat of a work in progress, but it looks like it's mostly 
complete now.  I'm not sure as of what version this was the case...
