Macros are not processed inside .js/.mjs files. about swc-plugin

It's not a limitation of macro nor swc plugin. It is how your build pipeline process js/mjs files. It seems your configuration just skip applying SWC to them. Start from there.

I forked the lingui repo and modified the react-swc example:
chrischen/js-lingui@88e8e19

If I simply swap out @vitejs/plugin-react-swc with @vitejs/plugin-react (which uses Babel) then the lingui JS macro works with used from a vanilla .js file.

Are you saying the issue is probably in @vitejs/plugin-react-swc since with Vite I don't really configure the build pipeline apart from the plugin? If so I will open this issue in the vitejs repo.

Yes, it is. They might skip js/mjs files because they don't need transpilation by theirs opinion.

FYI: https://github.com/vitejs/vite-plugin-react-swc/blob/main/src/index.ts#L206-L217

Ok I will cose and re-open the issue with them and see if they are open to changing it. My understanding is that SWC can be used for Macros, and macros can be used with vanilla JS files.
