The short answer is no. Imagine, if you will, a young married couple. She is a dog lover of the very worst kind. He never cared for dogs but begrudgingly agreed that they could have a dog. She named it 'Baby.' He, on the other hand, never called it anything but 'damn mutt' and that became his name for the dog. One dog, two names.
A function, by definition, maps any value in the domain to a single value in the range. One dog, two names violates this element of the definition of a function.
