I am fitting a toilet on a wooden floor in my cloak room. Below the wooden floor is a 2 foot gap.Can I drop down the 110mm soil pipe down to the concrete foundation then run the 110mm soil pipe flat for 4 metres then when outside of the house have it fall away to join the drain?.Any suggestion please.

You can, but it'll most likely block before too long. The pipe needs a constant fall, 1:40, all the way.
1:40 is the recommended minimum though you can still have success with much less fall provided you are very accurate. It also makes a difference how 'busy' the pipe run is.
For example, a 6m run of plastic pipe will run smoothly with as little as a few inches of fall provided it is arrow straight with no branches or such like.
However, running level for any distance is not a good idea.

Have you considered a saniflo, not ideal, but is ok!

Sorry, but unless a 4" drain was absolutely impossible I would never entertain a Saniflo. They are the devils own work when they go wrong. 
Macerators..NOOOOOO.
I admit its not the best idea! But if there is no other way, then it canserve a purpose.
