I'm studying use cases for Cochran-Mantel-Haenszel (CMH) test. All the examples i've found deal with 2X2 contingency tables. I'm wondering if CMH test is applicable for tables larger than 2x2?

Yes you can. You can read some of the theory on recent extensions of CHH tests by Rayner & Rippon
For 3 dimensional table examples you can look at Mangiafico's website
And for doing it in R the CMHtest function is a good start
