Yes, so long as you use full userdata created by lua_newuserdata.  Just 
create a userdata the size of your pointer and put the pointer inside 
the userdata.

The light userdata cannot have a metatable, so it cannot have an index 
event.

There are examples on the wiki that use these functions from the auxlib:

LUALIB_API int   luaL_newmetatable (lua_State *L, const char *tname);
LUALIB_API void  luaL_getmetatable (lua_State *L, const char *tname);
LUALIB_API void *luaL_checkudata (lua_State *L, int ud, const char *tname);

Cheers,
