Thank you.

No. Not via xdmcp. 

But you can use ssh to build an other session managment. 
- Create RSA/DSA keys for ssh.  This will allow you to connect to the linux
  host without providing a password (but the private RSA key)
- start X with 
  export WINDOWMANAGER=gnome
  xinit /usr/bin/ssh -X remotehost .xsession -- /usr/X11R6/bin/XWin :0
This starts the Xserver adn connects via ssh to the remote host and starts a
X session with the local server as output device.

Maybe you have to give some extra options to .xsession or use another startup
file like .xinitrc or /usr/X11R6/lib/X11/xinit/xinitrc or even better 
/etc/X11/xdm/Xsession gnome.
