In general wasm only requires an interpreter. But in the case of Unity web, there's JavaScript glue code that requires browser APIs that allow it to actually render.
There's other wasm runtimes that don't require a browser, but presumably you can't run the same Unity wasm binary in those runtimes and expect a scene to render.
