"Scotch whisky is made from peat dried, malted barley that has been fermented and distilled and then blended with corn rye whisky. The barley whisky is distilled at 140 proof and the corn rye at 180 proof."

This definition is certainly not the definition used in the UK. There are of course standards as to what constitutes a proper whisky in Scotland but any whisky made to the legal standard in Scotland is called Scotch whisky. Scotch simply means Scottish and does not dictate the type of whisky. The single malts are Scotch as are the other four types of Scotch. ie the blended malts; the blended whiskies, the blended grain whiskies and the single grain whiskies.
