No it is not. Calicos, to dumb it down, have white on their pelts while tortoiseshells only have black and orange. Typically you'll only see this in females as the black and orange genes are on different X chromosomes, but this can happen in males as well if they are chimeras (2 fertilized eggs fusing together) or if they have 2 X chromosomes as well as a Y chromosome due to a faulty egg, and this will make them sterile. Now, the white fur can be seen in both genders as the white fur as the gene (Ss for piebald, tuxedo, Snowshoe pattern, etc., of which there is one recessive gene) needs only to have either both X chromosomes or either the X or Y chromosome to have one dominant and one recessive gene for the white fur to occur. As you can see, there is a huge difference between whether they have white fur or not.
