The answer is a resounding maybe. If you activated with a Microsoft account or if there’s a TPM chip, the chances of it still working increases. There are different kinds of licenses, but if it fails, there’s a better than not chance calling MS support and just telling them you had a hardware failure on your laptop and you need to reinstall, they’ll get you going. Not a guarantee though. And I’ll caveat and say this information is a couple years old (I don’t work in tech support anymore).

You can just reactivate by troubleshooting your activation in Windows.
No need to call Microsoft about it.
The multiple posts of people not being able to do that should have made it clear that doesn’t always work.
