I have a Thinkpad T460. I thought I ordered it with the WLAN card (Qualcomm Snapdragon X7 LTE-A Sierra Wireless MC8355) but I didn't. I want to upgrade it now. Can I purchase that card and install it myselfor is it integrated to the main board?

There is some mix in your post.
WLAN and WWAN (Qualcomm Snapdragon X7 LTE-A you mention) cards are different types. WLAN (wireless LAN access) means WiFi. WWAN means internet access via cellular operator networks.
Sierra Wireless MC8355 card isn't a Qualcomm Snapdragon X7 LTE-A type card. It's a Sierra's name of the Qualcomm's prototype - 3g modem Gobi 3000.
T460 doesn't support legacy 3g modems, mc8355 including. It supports new wwan modems in the m.2 formfactor:
- Sierra Wireless EM7455, Qualcomm 4G LTE-Advanced/HSPA+/UMTS/GNSS, for worldwide networks
- HUAWEI ME906S, LTE/WCDMA/HSPA/GSM/GPRS/EDGE/GNSS, for Western Europe
You can purchase and install wwan card yourself. Make sure wwan antennas set is installed too, i.e.the laptop is wwan upgradable. Service p/n (FRU) of the Lenovo authorized card em7455 is 00JT542. Do not try to install that card with another p/n, for differant brand - T460 will not allow to use it w/out a lot of tricks.
Do it well, worse becomes itself
