This is an emphatic no.
Jesus’ teachings conflict with the Four Noble Truths of Buddhism.
He does not teach that all life is suffering, He teaches that the origin of suffering comes from sin (the primal sin being pride). He teaches that God must be asked for forgiveness of sins, but He also doesn’t teach that this will relieve temporal suffering.
Christ taught in the resurrection of the body, not the reincarnation, nor the cessation of existence ( Buddha’s teachings for the soul weary of reincarnation).
Anyways, there will be shared teachings in Buddism as a result of natural theology. But this does not make Christ a Buddhist.

Post Script:
After reading over the replies to the article, Mindship replies well. One thing involved with the article is the unknown years of Christ. There is no evidence that Christ had not taken up His father’s occupation. But Christ is referred to as a Nazarene, as in, one who is from Nazareth. Christ would have likely lived in the area to receive this unofficial citizenship. He also would have been recognizable to the people of His community “Mat 13:55: Is not this the carpenter’s son? Is not his mother called Mary?”. This is more of a “is He insane?” as opposed to “who is His folks?” wording.
