Suppose I'm writing a report where I often refer to a particular training dataset and a particular control dataset.

Would it be grammatically correct to refer to them as to the Train dataset and the Control dataset, respectively?

    "Training" and "Control" yes. This is common.

There is a useful convention in legal writing on creating specially defined nouns for the purpose of a single document or a single set of related documents.

"The data set numbered 123 and entitled "Training Dataset for Introductury Calculus, catalog number M101-M102" (hereafter the "Training Dataset") ..." exemplifies a device that lets you exactly define a word or phrase outside its accepted meaning and still use the same word or phrase in its accepted sense by avoiding the initial capital letters.
