What this will do is take out the aromatic compounds and oils.
One of the negative things though with coconut milk is that is has roughly 23% fat content. The milk can also be used to produce virgin coconut oil by controlled heating and removal of the oil part.

No, they cannot at all.
It is way too fatty for them to drink and therefore should be avoided.
