Definitely no. Look up the definition of Peyronie's Disease (capitalized because it is named after a person-proper names are generally capitalized).
"noncancerous condition resulting from fibrous scar tissue that develops on the penis and causes curved, painful erections"
Such fibrous tissue might possibly cause differences in length, but a difference in length is not definitive. It is the existence of the tissues that defines Peyronie's Disease. Differences in length between stretched and naturally erect are common and generally indicate nothing at all.
