No.
One license, one system.

And further, that laptop license key is tied to that particular laptop.

Your new system needs its own valid license.
Just part of building a PC. Just like buying RAM or a motherboard.

you can use windows without key, youll just get watermark and some limitations on personalisation settings, like no dark mode
