IMHO a full keel is a traditional long keel running from stem to sternpost - ie https://www.yachtsnet.co.uk/archives/heard-35/w50205-ashore-fwd.jpg

A cutaway long keel has a bit of the forward keel area cut away to reduce the length of the keel and hence improve manoeuvrability (and reduce wetted area), most Folkboat/Stella/Twisters/Rustlers have this. A Vancouver - https://www.yachtsnet.co.uk/archives/vancouver-28/m51106-ashore1.jpg has a fairly extreme version of this but is still clearly a long keel boat.

So a long keel can be a fairly wide range of shapes, but not all are the same.

Can someone tell me the difference?

Sadly I lost where (got to love FB) but some one was busy telling the world it was different and can editors not get it right?
This was the article:
"How I sailed around the world in my 32ft yacht" - Practical Boat Owner

I was always took the 2 to be the same like Vang/ kicking strap, boot / trunk, bonnet/ hood.

Go on someone enlighten me PBO doesn’t even mention long keel

Keel types and how they affect performance - Practical Boat Owner

While I don't think it's definitive, the diagram in the PBO article seems to cover it.

A full keel to me is one that runs from transom to forefoot and was the standard in the days of wooden boat building where it was integral to the structure, and the ballast might be internal or external. A full keel will be a long keel, but long keel can cover a lot of variations as in the diagram, and is not necessarily the full length of the boat and not necessarily with the rudder on the aft end of the keel.

Like many descriptors, long keel and full keel are not precise!
