It is characterized as:
A disorder characterized by eccentric behaviour and anomalies of thinking and affect which resemble those seen in schizophrenia, though no definite and characteristic schizophrenic anomalies have occurred at any stage. There is no dominant or typical disturbance, but any of the following may be present:
Inappropriate or constricted affect (the individual appears cold and aloof);
Behaviour or appearance that is odd, eccentric, or peculiar;
Poor rapport with others and a tendency to social withdrawal;
Odd beliefs or magical thinking, influencing behaviour and inconsistent with subcultural norms;
Suspiciousness or paranoid ideas;
Obsessive ruminations without inner resistance, often with dysmorphophobic, sexual or aggressive contents;
Unusual perceptual experiences including somatosensory (bodily) or other illusions, depersonalization or derealization;
Vague, circumstantial, metaphorical, overelaborate, or stereotyped thinking, manifested by odd speech or in other ways, without gross incoherence;
Occasional transient quasi-psychotic episodes with intense illusions, auditory or other hallucinations, and delusion-like ideas, usually occurring without external provocation.

The answer to your question is yes it can. To quote a teacher at a specialist school "You've got a brain (Autistic or Not) you can get a Mental Health Personality Disorder". I had this along with Borderline Personality Disorder after a nervous breakdown at work. This Personality Disorder was slowly manifesting over about 2 years before before I left work, it is clear that I have Autism from my early development (Just checkout my early development page) and I can't see why this "invisible" barrier must come up when dealing with someone who could both have Autism (A Developmental Disorder) and Schizotypal Personality Disorder (A Mental Health Disorder).
Yes this warped disturbed "Magical Thinking" was becoming more and more invasive and prominent as my mental health was getting worse. I remember having a massive episode in a public area it was scary (I had both depersonalisation and derealisation) this along with the psychotic episode was in a way a cry for help. My reality was in a mess but thankfully through the help of my family I got through this, I'm very thankful for their on going support and help.
Autism and Mental Health problems must be taken seriously and sensitively. The specialist must have knowledge in Autism to be able to help effectively and pro-actively sadly I never got this attention but my hope is in the future this becomes the mainstream!
