As long as Jesus obeyed the rules that a human being must obey to remain healthy (which is equivalent to God's law), he would have lived forever as a human, because his body had not inherited imperfection from Adam, so Jesus did not inherit the natural death.
That he could have lived forever (eternal life) is not the same as he was immortal. A human being can live forever in appropriate conditions and following the rules (as if it were his body's instruction manual)... but a human being cannot live without oxygen, without food, without water to drink, at extreme temperatures, if seriously injures certain vital organs, if the external pressure is extreme, etc.
Human beings cannot be immortal, because they are physical and depend on external factors which God keeps stable. So although Jesus may have lived as a human forever, he was not immortal while he was human.
Angels, although they are spirit, are not immortal either. Jesus received immortality from the Supreme Creator after surviving all the tests to which he was subjected, and showing full obedience to God, his Father, the original source of life.
