Dell has not used whitelists for wifi cards -- as long as the card is in mini PCIe format (not the current M.2), it should work fine.  
Hi: I was given a Dell Latitude e4200 and I installed W10 Pro 64 bit on it. It runs very nice.  Everything works. I had to use the W7 drivers for the SD card reader and fingerprint sensor. W10 installed all the other devices. This e4200 has the single band Dell wireless G HMC form factor card, and I have a Broadcom BCM943228HMB 802.11abgn 2×2 Wi-Fi Adapter, Broadcom Bluetooth 4.0 Adapter that I removed from my HP 350 G1 notebook Intel 4th gen core processor) when I upgraded the card to an Intel 7260AC. On a HP notebook made around the same time as the Latitude e4200, the HP notebooks had BIOS whitelists which prevented the installation of any other model Wi-Fi adapter not listed in the service manual from working. Does anyone happen to know if the Broadcom card has any chance of working in the Latitude e4200? The card is easy to remove and replace, but I hate to mess with those delicate antenna wires, and there is no use in trying it out if someone knows that it has no chance of working. Thanks!
