是的，although和though从句也可以省略主语和动词be 的，即当从句主语与主句主语相同且从句谓语含有动词be时，可以省略从句重复的主语和动词be。即：
He is very experienced though young.
=He is very experienced though he is young. 他虽然年轻，但很有经验。
又如：
Although (he is) still young he is going very grey.（张道真语）
Although (he was) exhausted by the climb, he continued his journey.（夸克语法）
