Have you actually tried opening a file outside of /sdcard? It just works (and, uh, that's how applications can access their data as stored in /data).
(Android relies on linux processes, not on the VM, to enforce security. If the process is allowed to do it, there's no security reason why an app running inside the VM wouldn't also be allowed to).
