Set up an openvpn tunnel from the remote unattended machine to the 
centos box.  If you can set up port-forwarding on it's NAT router, you 
may be able to originate this connection either way.  If you can't, use 
a keep-alive setting on the natted side to make sure the connection 
stays active.  Then you can either do the same on the laptop with 
appropriate routing or you can run freenx on the Centos server and 
connect to it with the nomachine NX client on the laptop.  In the latter 
scenario you would run rdesktop or vncviewer on the Centos server but 
the display would be on the laptop.
