Depends on your webhoster and has nothing to do with SEBLOD or Jooomla or PHP or any other things. If the databases are in the same webspace you probably can access each from any website within the same server. In different webspaces/servers you need a database that is open and accessible from outside which is a high security risk and therefore not common practice hence most likely you will fail to do so in that case.
