Not without changing the src code.

Look for the hostx_set_win_title() function in hostx.c and ephyr.c, both
in the hw/kdrive/ephyr directory.  Eg:

http://cgit.freedesktop.org/xorg/xserver/tree/hw/kdrive/ephyr/ephyr.c
http://cgit.freedesktop.org/xorg/xserver/tree/hw/kdrive/ephyr/hostx.c

That said, the window name is just a property.  You can use xprop(1) to
query and set properties for any window, so you can use that to set the
WM_NAME and/or WM_ICON_NAME STRING properties.  (There are also the
UTF8_STRING properties, _NET_WM_NAME and _NET_WM_ICON_NAME.)
