Conceptually the idea of a "VST" works on either platform, because VST is an API. However, VSTs are distributed as executables targeting a specific platform, and almost no VSTs are compiled natively for Linux.
If you're already content with Reaper as a DAW, use "yabridge" which runs VSTs in WINE. It's virtually perfect for most purposes. Getting Linux audio set up for low latency is another Linux rabbit hole, though.
