Is it possible for chronic leukemia to turn into acute leukemia?

Yes. Yes, chronic leukemias, usually after a relatively long period of evolution, may turn into an accelerated phase, sometimes called "blast" phase, which is equivalent with acute leukemia. This transformation indicates accelerated progression.
Yes. CML can turn into acute leukemia if not treated with one of several modern drugs called tkis. Tkis will prevent this transformation for at least 80% of patients for more than 10 years.
Yes. There are 2 common types of chronic leukemia, chronic myeloid and chronic lymphoid leukemia. With current treatment, CML now rarely converts to acute if treatment starts early. After a long time, cll can transform to more aggressive leukemias or related cancers.
