Because they are similar models perhaps.

the T420s has whats called a BIOS whitelist, this means that unless the VEN and DEV strings are burnt in the bios the card will not work

If the cards are both the same model intel wireless then the VEN and DEV id would match and therefore it would work

Take a look at the Lenovo website, if there is a wireless driver for the model card you have. Then it will potentially work.

You can try. If the card does not work, you would have to edit the BIOS and that is not something I recommend.

Why do you need to change?  The cards should be similar in terms of performance.

T450 has Wireless adapter from Inter whereas T420 has Sierra according to Lenovo Support Website:

If you want to swap the wireless cards, you would need to install the correct driver.

Intel Wireless Adapter in T450 is compatible up to WIndows 10 64 bit, whereas Sierra is compatible up to Windows 7 64 bit according to Lenovo Support.

So if you are going to swap the Wireless adapters, you'd need to deal with the driver and also depends on the operating system.

Sierra is a cellular card, not the Wi-Fi card. That would be a different card.

@John, thank you for pointing it out.

My comment above needs to be updated as:

1- Make sure the Wireless cards use similar drivers (rare)
2- Both have Intel Wireless LAN
3- T420 Wireless LAN compatible up to Windows 7 (64 bit) and T450 up to Windows 10 (64 bit)
4- You might have to deal with the driver according to the operating system.
5- You might be able to find a driver for T420's Wireless adapter from Intel (not really sure but possible)

To find out compatibility, visit the support websites above.
Most likely, you will have to deal with the driver after swapping.
