Yeah, definitely. But for a fair comparison I think you have to look at how .NET did things before async/await hit the scene. And, for that, the aspect of the design in question is quite similar between the two.
Early .Net is hardly an independent data point from early Java. Not only was .Net directly influenced by Java, it also had to support a direct migration from the Microsoft JVM specific Visual J++ to J#.
