You can not determine for sure if a person with black or brown eyes is a homozygous without a genetic test even if as far as you know all the relatives of that person have brown or black eye. Therefore the mom could be heterozygous and if the dad is also heterozygous, then yes, their child can have green eyes.

Yes it is possible because the eye color is determined by more than one gene.  The father's grandparents could have had green eyes.  My father had brown eyes, my mother has hazel eyes, mine are green.

Eye color is polygenic (coded for by several genes) therefore it is possible considering that they carry contributing alleles for the said trait. The more contributing alleles (alleles which codes for a darker eye color) the darker the eyes would be. Therefore whatever the color of the eyes of the parents are not the bases instead it is the number of contributing alleles passed on to their offsprings. This is of the same inheritance as height.
