>>716003459Samurai wasn't a defined term like it came to be after Hideyoshi.
If by 'samurai' one is referring to a random warrior than sure, he was, but only according to Nobunaga, who probably did it as a joke against the social order.
If one is thinking of the the bushi (ๆญฆๅฃซ) proper, the elite warrior noble caste, then 100% no.
