Can the Tenseigan be transplanted? Is the Tenseigan able to get transplanted? I've tried Googling it but it did not give me the results I was looking for.
Logically speaking, the Tenseigan should NOT be able to get transplanted, as long as the receiver isn't of the Otsutsuki.
According to a Quora page I found:

The Tenseigan is a dojutsu that can be awakened by a combination of a Byakugan and the Chakra of an Otsusuki clan member. The Tenseigan is a dojutsu that can be awakened by a combination of a Byakugan and the Chakra of an Otsusuki clan member.

Considering the fact that Tenseigan can only be awakened when a Byakugan is tied to the chakra of an Otsutsuki Clan member, it should not be able to get transplanted because once taken out of the eyes, it is no longer tied to Otsutsuki chakra of any sort. This is assuming the receiver of the Tenseigan isn't Otsutsuki themselves.
