That would be unfitting. OTP started as "Open Telecom Platform", but today the long form is not in use anymore. To quote Wikipedia (with emphasis from me):
"The name OTP WAS originally an acronym for Open Telecom Platform, which WAS a branding attempt before Ericsson released Erlang/OTP as open source."
Today, OTP is the name.
To avoid confusions, it would have been best to add "(Erlang)" before the title.
