If God can do anything can he create a boulder so heavy that even he couldnt lift it?
If boulder means what I think it means, an enormous rock, linguee-translate is not clear in that, then I guess the answer to your question is yes, that he can.
Why couldn't he?
He can do everything according to your question, why not creating a boulder so heavy he couldn't lift it.
Of course he could create a device to lift it if necessary or create himself the power to lift it afterwards, if the boulder would cause any problems.
