I might be biased with some exposure to Norse and Old English too, so I don't know whether Norwegians without that would recognise nearly as much (or little) Icelandic given how much Icelandic still takes from Norse.
I understand the western Norwegian dialects (/ nynorsk) have a much stronger old / west norse influence so are closer to Icelandic, maybe you are from those regions or are familiar with these dialects?
