Chrome supports binary extensions on all platforms. But I cannot decide whether Chrome OS supports them too...
回答1:
Nope, they are disabled on purpose.
See this, this, this.
回答2:
They don't support NPAPI, but they do support the new native client architecture NaCL.
For more information regarding the difference:

If your binary extension uses PPAPI rather than NPAPI, it will definitely work on Chrome OS.
