It depends on what you mean by "context".
If you don't have any kind of OS running, you have one thread and
interrupt handlers, you can safely call lwIP RAW API functions from your
main thread. It is not safe to also call from interrupts. If your
application depends on interrupts, just set a flag or equivalent and let
the main thread react to that.
If you have an OS, you have to keep everything on one thread or use
another API.
