Advice on refurbished Thinkpad T420 Vs Recent budget laptops sub 200GBP range

[F1demon]

I'm planning to buy a refurbished Lenovo T420 for under 200 GBP.

Its specs are: 14" Lenovo Thinkpad T420, Core i5-2520m, 4GB RAM, 320GB HDD, Windows 7 Pro, New Battery. My question is:

1) Whether these machines can run Windows 10 smoothly &
2) Does it make sense to purchase a refurbished machine esp this brand? I've had good experiences with a previous X210 so, I'm wondering if it makes sense to go in for this machine?

The things I like about the Thinkpad are its- -ruggedness
-good battery life
-Ports
-non-chicklet type keyboard

I'm just worried that its OS is Windows 7 which is no longer supported by Microsoft and since I would need to run applications like Office 360 which are designed to work with Win 8+ onwards?

Any advice would be appreciated!

Thank you.

Win 10 Pro will run 100% fine on the T420. I just sold one that my mom was using, exact same spec as yours, only difference being I added a mSATA drive for her OS and programs. I did the free upgrade for her from Win 7 Pro. There were zero compatibility issues and the machine ran quick for its age. The only reason she sold was because I got her an upgrade.

Edit, she was also running Office 360 without any issues.
