No it's not. From the National Autistic Society:
"Asperger's syndrome’ (often shortened to Asperger’s) is no longer used as a diagnostic term for autism and is considered controversial due to the history of Hans Asperger, which is summarised below.
Historically, Asperger syndrome was used as a diagnostic term for some autistic people who did not also have a diagnosis of a learning disability. Broadly, it is now agreed that what was referred to as Asperger syndrome is part of the autism spectrum and there is no need for a separate term.
Some people who received a diagnosis of Asperger syndrome continue to use this terminology to refer to themselves. Others do not, usually for two reasons: because the term is no longer used officially; and because of revelations about the Austrian psychiatrist Hans Asperger, who Asperger syndrome was named after and who was complicit with the Nazis."
