Windows 10 can reinstalled and it works even without an activation key. From what I understand, some features are disabled but the Windows 10 will work just fine. But if the machine came with Windows 10, there should be some activation code somewhere on the laptop or in the paperwork that came with it.
In my case, I had a Windows 7 DVD from a work laptop. My company installed their version of Windows, but they still have me that DVD when I got the new laptop. I was able to use that code to activate Windows 10 in a PC that I built myself, and now I upgraded for free to windows 11.
I think Windows is not really that strict about activation these days, my point is older codes from Windows 7 DVDs used to work back in 2020, I don't know if that still works now, but as mentioned above, you should find a code somewhere or get a new code is really cheap on eBay these days.
