I don't think this is true at all. I don't think VSCode has any Visual Studio code in it at all, but that's probably why they are able to be so nimble with it - no legacy cruft.

I work on VS Code. You are correct; the core VS Code editor does not share code with regular Visual Studio. However many tools and libraries are shared between the two. TypeScript and JavaScript language support for example is powered by the same TypeScript library in both VS and VS Code, and this library also is used by Atom, Sublime, and many other tools.
