z/OS does not have a X Window (singular, not plural, a common mistake) server.
The "server" in X is the software which provides access to the display and
keyboard. The X client is the application code which talks to the server. z/OS
does support X client code. At one time, there was a X Window terminal. That
was basically some "smart" hardware which accepted X protocol to drive a
graphics display.
I think the answer you are looking for is "Yes, you can run a program which is
an X client on z/OS." I do it. I have a Linux desktop. I use SSH to connect to
z/OS. And I set ssh to set up a "reverse X tunnel". Doing this causes a z/OS
UNIX command prompt to appear on my desktop. It also causes the DISPLAY
environment to be set up correctly. Basically it causes the ssh server on z/OS
to "listen" on a dynamically assigned port (in my case, and by default,
starting with port 6010). The SSH server then causes any connection to this
port to be tunnelled back to the desktop over the ssh link.
You can also use telnet, but it is a bit more difficult. You need to set the
DISPLAY environment variable to the proper value
export DISPLAY=ip.address:XportNumber . And you must also set up the X server
on your desktop to listen on the XportNumber port. This is normally port 6000.
On my system, I do this automatically in the /etc/profile file.

SSHD="No"
set . $(ps -o args -p $PPID)
case "$3" in
*telnet*) DISPLAY="$5";;
*rlogin*) DISPLAY="$8";;
*sshd*) SSHD="Yes";;
*) DISPLAY="None";;
esac
if [ "$SSHD" = "No" ]
then
DISPLAY="$DISPLAY:0"
if [ "$DISPLAY" = "None:0" ]
then
unset DISPLAY
else
export DISPLAY
fi
else
export DISPLAY
fi
export SSHD

You can also use MS-Windows if you have a X server on it. MS-Windows does not
come with an X server. I have successfully use Cygwin's X server.
