of course he can
when obito warped kakashito the other dimension kakashi used kamui on himself to go to the real dimension
so if he used kamui on himself in the real dimension he will go to the other dimension(the same thing)
and it is so good defense as he can cancel his existence and go to other dimension to avoid nearly any attack even
the meteor,the dust,the giant bijudoma,c0,hirudora,c3,jiubi's doma........etc(any attack)
and that why some member try to get ride of this ability from kakashi as it is so good defense
and i think he can come in other place as obito do (go to od and come in other place)
as kakashi said tobi has teleporting stronger than minato's one as soon as he disappeared and go to other dimension
and then tobi came in other place
that mean when someone can go to other dimension ,he can come in other place
