I just would not take the chance as your Chi is not used to the puppy and he could get rough with the puppy that small. For safety, I would separate them.
But I would solemnly rethink leaving a baby Yorkie that young alone for any period of time as they can get low blood sugar very quickly and even die. Being a baby, he could get a tummy upset and start vomiting/having diarrhea and dehydrate quickly also. It is just not a good idea to leave a Yorkie puppy that age unattended. He's a very young baby and needs pretty constant oversight.
