Hi Marek,
I guess it's pin 47 which is the problem. All other pins look ok for the x201 (even the MCI_ pins). So you could try to cut the line on the card or remove the copper of this pin.
In your x201, the card should work in the WWAN slot well, except the MCI_pins are connector to the sim slock, but no idea if this is a problem ;).
The other solution would be, try to put the (x201) CL_DATA_WLAN/CL_DATA1 (me link) in tri state on the chipset side, but no idea if this is even possible on the chipset.
Best, lynxis
ps. x230 doesnt have a pcie capable wwan port
