The Apple Store online hardware store can be accessed from any computer any https://apple.com/shop

If you mean the App Store, to download apps, then you cannot. Windows Laptops have the Microsoft Store and Chromebooks have the Google Store. But you cannot get the Apple App Store on a non Apple computer.

The iTunes Application provides access to the iTunes Music, Movie and TV show stores.
