With enough time and fabrication, the Yanmar loader will absolutely fit. The question is how much fabrication will be required. Your CK25 is quite a bit larger than the machines Yanmar usually paired with that loader. It has over a foot more wheelbase and much larger tires. There may not be enough length in the loader from its mounting bracket to the bucket to clear your machine's front axle. It may be too narrow to fit around your engine and transmission housing. The bucket may be too narrow.
My suspicion is that by the time you are finished, you will essentially have fabricated a new loader frame from scratch and simply used the Yanmar's cylinders and bucket, anp perhaps the arms if you reconfigure the bucket.
