Hello Aa Fathur,
Upgrading your laptop from Windows 10 to Windows 11 should not be an issue if both of your devices are already linked to your Microsoft account with digital licenses. Microsoft introduced a feature called "Digital Entitlement" that ties your Windows license to your Microsoft account, but you will still need to have separate licenses in the account. The way that "Digital Entitlement" works is that when you activate Windows or other Microsoft software on a device using a Microsoft account, the digital entitlement is tied to that device's hardware. This means that the specific hardware configuration of that device is what's associated with the digital entitlement, not the Microsoft account.
