I sincerely doubt that there's anyone that takes 'God' to be literally synonymous with 'love'. When people say God is love, they are referring to His (or Her, or his, or her) infinite compassion, not saying that the terms 'God' and 'love' are interchangeable.

Put it this way: Earth is a planet. Not all planets are Earth, and when I say Earth is a planet, I don't mean Jupiter is an Earth.
