Let's assume your big map scale is 1:100 000 and the overview scale 
is 1:1 000 000.

Go to the first tab of the layer properties window and switch the 'Enable scale 
dependent rendering' on. 
For the CORINE layer set scale ranges: min=1 max=500000
and for the coastline set: min=500000 max=100000000 (or anything very high)

Now if the scale is =< 1:500 000 only the coastline is displayed. If is >= 1:500 
000, only the CORINE. Of course it works in the map canvas too, so don't be 
surprised that one of the layers disappears from it.
