As long as the same extensions exist in its repositories, yes. VSCodium has its own extension marketplace though, many of the most used can be easily found there.
You can also download the *.vsix file of the desired extension from either Github or Microsoft's extension marketplace and install it manually by clicking on "Install from VSIX" in the Extensions menu.
This obviously doesn't solve the update problem and it is also questionable if this is in terms with the "Microsoft Terms of Use" of the extension.
or just use the vscode marketplace in codium....
you can also just use openvsix, which actually contains everything you'll ever need
