		You can have, but this is not recommended.
Having a single oracle home for multiple EBS environment is not a logical thing..
 You create dependencies by doing such a configuration..
 
 For ex: if you patch one of your EBS 's Oracle Home, then all the EBS in your environment will get affected from that.
 
 So, it is not a good thing, I don't recommend it at all.
