Purchase a Windows 10 operating system for an older Windows 7 Dell Laptop

I have an older Dell laptop (about 4 years old) that had Windows 7 operating system on it. If I purchase a Windows 10 operating system, and download it on my older Dell, will it work ?

I do not want to have to purchase another laptop with Windows 10 already downloaded on it, if I do not have to.
