Eh? I didn't know that only one singular slot was in question here, or that the conversation had shifted from talking about WiFi to instead talking about cellular. My own ThinkPad absolutely has independent slots for WiFi and cellular cards, and they look similar but they aren't even electrically compatible. (One is a mini PCIe with PCI Express and without USB, and the other is mini PCIe with USB and without PCI Express.)
