When I checked the Lua 5.0 source a while back, there was nearly 1K of
string data for error messages, etc, which might not be needed if your
device doesn't have text output. It is a bit of a nuisance to go through
all the luaG_runerror calls and others to change the strings to nulls but
it might be worth doing if you are really stuck for space. And of course,
you could reduce the error routines themselves to stubs if they are not
doing anything useful.

So, that gets you down to 39K - just another ten more techniques like this
and you'll be there ;-)
