Maybe.
Kontact is correct that with a 11-30 cassette you'll be out of the max (total) capacity of 33 for your new crank. However Di2 won't shift to the last two small cogs on the rear when you are in the small front. So that'll probably be a 13 cog and that possibly makes you okay.
Not certain what Shimano says about figuring total capacity for Di2 and other setups where they said not to use those cogs when in the small.
Learn what the numbers mean and then you'll make better decisions about what to get.

However nothing here was about cross chaining. It was about finding the correct size rings that will work with your existing rear DR and whether you'd be able to size the chain properly and not have too much or not enough slack in it.
