Not natively no.
As mentioned in that thread, a device that does wireless to wired and plugs into the Z/MX WAN port could in theory work but I wouldn't go for that option in a production network.
If you can't use a wired ethernet network, i would suggest using a cellular device that supports LAN clients and connecting the LAN port on that device to the WAN port of the Z/MX. You could use something like the Netgear LM1200 for a Z series device on the go.
