Yes. The maximum weight of tiling per m2 on Gypsum Plaster is 20kg/m2 or 32kg/m2 on Gypsum Plasterboard direct (i.e. without plaster skim) [See page 6 of the BAL Sitework Guidance literature]. As a general rule, remember to allow approx. 2-4kg/m2 for weight of adhesive and grouts in addition to the weight of tiles.
