Is lymph fluid the same as a lymphocyte?

No, lymph fluid is not the same as lymphocyte although both are part of the lymphatic system. 

Lymph fluid is a colorless watery fluid that flows throughout the lymphatic system. It supports overall health by carrying proteins and nutrients to cells and tissues and collecting fluids from tissues, which are then returned to the blood. 

Lymphocytes are white blood cells that help fight infection. Lymphocytes may be present in lymph fluid. 

Lymph fluid and lymphocytes work together. Lymph fluid picks up cancerous cells and foreign invaders such as viruses and bacteria and lymphocytes often help to dispose of these unwanted intruders.
