I took a quick look at the specs and the T460 has 2 cores and uses DDR3 ram, so even though Linux is much lighter on resources than Windows, this laptop might not last you too long, considering how heavy even basic web browsing is these days. This computer will choke if you have a lot of tabs open, especially if you have things other than the browser open. I also noticed it has TPM, so just double check that you can replace the OS on this particular machine.
An alternative would be the T480, which would give you more mileage but can’t usually be had for under $100 like the T460.
Glhf!
