Bismihi ta'ala
Yes, from a shar'i perspective, if no lust or inappropriate comments or gestures are made about someone, you can say "so and so is handsome/beautiful". Is it a good idea, I don't think so. One's physical appearance should not be the point of conversation between people, especially if they are non-mahram and opposite gender.
It could be used against you, or taken out of context, or understood with other intentions.
And Allah knows best
