Excerpt from the official requirements to develop a Windows 10 app:

Windows 8.1 and Windows 7 support
If you choose to develop Universal Windows apps with Visual Studio 2015 on a platform other than Windows 10, these are the restrictions:
- Windows 8.1: You can’t run the app locally (only on a remote Windows 10 device). You can use the emulators in Visual Studio, but not the simulator.
- Windows 7: You can’t run the app locally (only on a remote Windows 10 device). You can’t use the emulators or the simulator in Visual Studio either.

Neither a developer, nor any normal user can run Windows 10 apps on Windows 8(.1) or 7.

No, It is not possible, because UWP apps are not backward compatible. Windows 10 can run Windows 8/8.1 apps but not vice versa.
