Yes, I guess so.

I'm not sure that's a fair comparison, as "Crown Corporations" as I've read in the Wikipedia article you linked to are historically linked to the systems descended from the UK's monarchical, parliamentary form of governance, perhaps with different charters and rules and laws to abide by, that most likely differ from the government owned corporations here. We probably have had actual Crown Corporations during the colonial era before the foundation of the now United States and the revolutionary break away from the British Crown. Not to mention that the form of government in the US is (or is suppose to be) a federal constitutional republic, and is not parliamentary, nor do we recognize Elizabeth II as our Queen (conspiracy theories notwithstanding).
Of course we do have government owned corporations which are similar, though before this "great merger", they were often the creation of the government. Some were former departments, like the Post Office Department, which is now an "independent" corporation (though it was created via an act of the Federal government). Another is the hybrid private-public
National Railroad Passenger Corporation, which is more commonly known here as "Amtrak", which is a nationally run system of rails and passenger cars. I'm sure Canada has something similar.
Now, I may have arguments on those things in principle, however, the merger of state and corporate power that I was alluding to before is formerly independent companies and corporations that are now either partially owned, or completely owned, and I've mentioned some of their names in
