It is impossible to squeeze toothpaste out of the back end of the tube and refill it with mayo. The back end of the toothpaste tube is designed to only dispense a small amount of toothpaste, which is why it has a narrow opening. Even if the toothpaste were somehow pushed through that opening, it would be impossible to push enough toothpaste out to fill the tube with mayo.

Yes, unfortunately you can. Toothpaste does not have enough of a taste or consistency to resist flavor transfer, so you may wind up with half a tube of toothpaste and mayo in the back end of the tube. You may also find bits of toothpaste in your homemade mayo, so be sure to shake it well before use.

Note: To refrain from transferring flavors, it's best to fill the tube with unused toothpaste and refill the remaining space with mayo after you have squeezed all of the toothpaste out of the back end. This will prevent any flavors from getting stuck in the tube.
