No you can't. This is because the Library is not exported with your movie as there may be unused elements. Thus Flash saves space by not exporting elements which are unused. As such, if you want to load a clip up at any time it must be somewhere in the movie so that it counts as a used object, (generally on the same frame makes it a lot easier).
Remember however that it doesn't have to be in the visible stage area. It can be off the screen and invisible to viewers.

Please don't rely on me reading my PMs either. Email me about important stuff.
