The only thing that can really confirm whether you are Z140 or not is to actually get the proper SNPs tested.
While those DYS markers you mention have their "Anglo-Saxon" and "Norse" looking values they don't always fit perfectly into these categories.
Also a good thing to remember is "Anglo-Saxon" and "Norse" in these contexts does not literally mean Anglo-Saxon and Norse. These haplotype clades were named to show their geographical pulls long before all these various SNPs had been discovered.
