True. This is a key strength of immunofluorescence (IF) known as multiplexing. By using primary antibodies from different host species (e.g., a mouse anti-A and a rabbit anti-B) and detecting them with secondary antibodies conjugated to fluorochromes with distinct emission spectra (e.g., green FITC anti-mouse and red Texas Red anti-rabbit), two different antigens can be visualized on the same tissue section simultaneously. A fluorescence microscope with specific filter sets can separate the signals, and the images can be overlaid to assess co-localization (if the colors merge) or distinct distribution. This is much more straightforward than trying to do the same with enzymatic IHC, where colored precipitates can physically overlap and mask each other. Advanced IF can even detect three, four, or more antigens using careful spectral separation and imaging techniques.
