No.

You'll need a modded BIOS in order to use a non-approved card.

T430 is harder to whitelist as they have the security chip and you need a hardware flash programmer...

The hardware flash programmer isnt expensive, I actually got one from ebay but the location of the chip to flash is hard to get to....it was too daunting for me so I ended up not doing it...
