Nope.

[hider=Actual Facts]I'm currently studying Japanese through my university, but if that isn't enough proof [url=https://en.wikipedia.org/wiki/Senpai_and_k%C5%8Dhai]Wikipedia[/url] and [url=https://www.google.com/search?q=senpai&oq=senpai&aqs=chrome..69i57j0l2j69i59j69i61j0.2020j0j7&sourceid=chrome&es_sm=93&ie=UTF-8#q=sempai]Google[/url] agree with me. A quick search says that out of the three main romanisations of Japanese, all use "senpai". There was one that used to use "sempai" but that was revised to "senpai" over 60 years ago.[/hider]

[@Halo] I'm happy that you are taking time to express concern for the misinterpretation of the Japanese language, but as someone who has been speaking Japanese almost their entire life, I have to make some tweaks to your explenation.
We use sempai and senpai together, actually. When we are addressing someone we admire as a tutor or teacher, we use [i]sempai[/i]. This term is used for a senior that you respect normally.
When using [i]senpai[/i], you would use it to address someone that you find as an upperclassmen or senior that you admire with a passion.
Some people interchange them in speech, finding that the person they are addressing fits both descriptions, and that's okay.

Edit: Excuse the mispelled words. I fixed them, but obviously my English needs help xD
