Just double checked in a Windows VM. These are available when searching WSL in the Microsoft Store. Some of these are for a fee. There are also a few results for terminal emulators and an X server.

- Ubuntu (18.04 and 20.04)

- Kali

- Debian

- Fedora (remix for WSL)

- openSUSE-Leap-15

- SUSE Linux Enterprise

- Alpine

- Pengwin (Debian-based and apparently optimized for WSL, and an enterprise version)

- Centos (7 and 8.1)

-
