What information can vpn provider see when I use wireguard?

[rosskan]

Hi guys
for privacy reasons, I never show my ip address to the vpn provider that I use on my main laptop. "But they keep no logs" I don't know that.

what I do instead:
I install vpn provider #1 on a crappy laptop that has windows 10. this is a laptop with a crappy processor and perhaps a broken screen but it doesn't matter. in windows 10 network settings, I send the vpn traffic from provider #1 to the ethernet port of the crappy laptop. I connect the main laptop with crappy laptop using an ethernet cable. on my main laptop I use vpn provider #2 using wireguard software.

what I am trying to figure is if I use the same crappy laptop but change my main laptop, and I sign up with a new account with vpn provider #2, and I use wireguard on the new laptop, can vpn provider #2 figure out that I am the same person? I guess what it boils down to is this: does wireguard share the mac address of the ethernet port of the crappy laptop with vpn provider #2?
