Yes, you can, BUT: If the markers between the alleged father and child match they are given a Parentage Index number that indicates how common that marker is among the population. Its very uncommon for a parent and child to exhibit more than 2 or 3 mutations (typically, there is just one) and all other locations must match exactly in order to support a biological relationship. As the language itself suggests, "cannot be excluded as a possible contributor" is not necessarily as powerful as "match". We always recommend including the mothers sample as well when submitting paternity test samples, just to be safe. However, DNA tests can also be used to exclude certain relatives from a family tree.
