Windows 10
Your laptop contains various files and settings. You can check the details by opening the relevant applications or using system tools. Yes, it's possible to move a Windows 10 license from one PC to another.
You can definitely do this. If you're logged in with a Microsoft account on your laptop, the Windows 10 license is linked to that account. You should be able to transfer it by visiting the activation page in settings and selecting "Add an account" using your Microsoft account. If you have the Windows 7 key, simply enter it and Windows 10 will activate automatically.
If your laptop came with an OEM license and you signed in using your Microsoft account, activation on the desktop might not automatically follow. The outcome depends on whether the license is still tied to the original equipment. Consider @Vishvas Sudarshan's advice to test activation on your desktop. If it succeeds, you're good; if not, you'll need to buy a compatible license from an authorized seller.
