Yes they can. The audience may not always understand Kenny, but his friends understand him just fine. Kenny is not mentally handicapped, his voice is just muffled by his hoodie. It is also possible for the audience to decipher his comments from the general context of the conversation and the tone and rhythm of his muffled voice.
Maybe Kenny wasn't the best example. I will grant you that. But the bolded part could still be achieved through just "hodoring". Just like all of Chewbacca's growls didn't need to be translated by Han Solo.

But we can't understand WHY Hodor is happy or sad, we can't understand if he might've had something meaningful to contribute to the conversation.
You can make a qualified guess. And that we can't know for sure exactly what he is thinking of trying to say, could make your imagination run wild, and therefore make it rather interesting to guess what is going on up in his head.

How do we access his quests?
That's assuming the companions will have personal quests. But I guess he could just point on a map, or if you go to a specific place he will start rambling and try and point you in a direction of what he wants to do.
Plaintiff wrote... How can we be sure if he himself understands what we're saying to him?
How about. You ask him to do something and he does it. Pretty simple.
Plaintiff wrote... What would be the point of engaging in dialogue with him? We can't discern his past or his likes or dislikes. We have no way of determining how to go about forging a friendship with him, unless he's constantly accompanied by an interpreter, which would just be an extra, unnecessary step in communicating with him.
How can Bodahn know that Sandal likes enchanting stuff. Sure conversations would be simple or perhaps somewhat pointless - that is what is making it a low cost character to include!
Plaintiff wrote... Dog's limitations mean that he has very little in the way of utility, and Mabari are supposed to be extremely intelligent. The player can only react with him in an extremely limited number of ways. Unless you're okay with a developmentally challenged charactger being relegated to fetching random trash and licking blood of your face,
Now that is kinda creepy. I don't see why this half wit character shouldn't be able to repair weapons, armor, enchant stuff, and so on (you can make up your own abilities if you please). Afterall there should be a reason why this character is brought a long on quests. Perhaps he is able to wield the meanest war hammer in the realm.
Plaintiff wrote... I don't see what they could offer that Dog cannot. And furthermore, I don't think I trust Bioware to implement such a character with the sensitivity and tact that ought to be required. Hodor doesn't sound like a sensitive or accurate portrayal of the mentally handicapped, he sounds like he exists to be a recurring gag.
A humanoid clearly opens up other possibilies in terms of storytelling than a dog. And really I could care less if a character is an accurate portrayal of something. I just want the characters to be interesting. Sometimes accurate and interesting is on the same side of the rope. Other times accurate is just boring.
