Unfortunately no, it isn't possible there are two case:
1) The app is released under your name. If you do this Apple sees you as the owner of the app and won't deal with or make payments to your client.
2) The app is released under the client's name. If you do this Apple sees the client as the owner of the app.
I imagine that most clients would want to release from their own account as they'll then "own the brand", since they'll be listed as the developer.
