\bABC\w*\b(?<!XYZ)

assuming your regex engine supports lookbehind assertions.

Explanation:

\b        # Start at a word boundary
ABC       # Match ABC
\w*       # Match any number of alphanumeric characters
\b        # End at a word boundary
(?<!XYZ)  # Assert that the previous three characters were not XYZ
