Only by dint of licentious interpretation.
No to be contentious, but this really isn't anything new.
A person carries a lot more than business papers on their laptop, including a lot of personal information. Any of that information could be obtained without leaving the country. There is then no particular purpose for searching such an instrument as there is nothing on it that could not be obtained domestically and therefore there are then no grounds for such a search. Any spy or terrorist who obtained information so sensitive as to require concealment could easily do so without putting it on the laptop. There is simply no benefit to such a procedure.
You also have the option of not taking a laptop with personal information on it with you when you cross the border.
It was the same before BO became president. It will be the same afterwards.
