It's not very common to play timbales sitting. Usually if somebody is playing timbal and using a bass drum they stand. However, it is becoming very common for the timbal player to also play drum set and timbales simultaneously, in which they would sit.
That being said, there's no reason not to. It might be awkward ergonomically but I'm sure people have done it.
