Technically, no because the "tin" in "tin can" is an adjective, not a noun. Through common usage "tin" used by itself in that context has become a noun, but if you're saying "tin can", it's the "can" that's actually holding something.To me a can is anything with a ring pull....but I use them pretty much interchangeably.
But isn't the technical term a tin can? So surely both 'tin' and 'can' are just abbreviations of the same phrase?
