There's no way without damage if the link has fallen off. Probably best to remove number plate and cut a hand-sized hole in bootlid behind. You should then be able to feel the linkage and pull it up. It's very stiff though. Don't try to lever the boot up, the latch is very strong and you'll do more damage than cutting a hole.

It means that the car beieves that the boot/trunk is open. Either the switch is broken or the latch hasn't closed properly.
The cable between the latch and the handle may be broken or needs adjustement to shorten the cable so that the latch will fully release.
Use a set of pliers to pull the cable even if the plastic latch is broken...
