I'm about 99% sure that's not the case (give or take 1%).
From what I can gather, the word 'undertaker' really does come from the verb 'to undertake' which means to accept or take charge of a task or duty. I'm pretty sure we'd still call them undertakers even if their job was to hang the dead from trees instead of bury them.
