Yes it is well possible. Try this at home: prepare an aqueous solution of table sugar (maybe not one litre, you cup of tea may be, in terms of volume offered, sufficient). Than look out for table salt, add some, and stirr the liquid. Does this solution saturated (in terms of sugar) dissolve any salt?

After this experiment, do not drink this "beverage". Rinse your cup of tea in the sink. Beside, the taste is repelling.

There are instances where the presence of one substance (your solute, here: sugar) in the solvent (here: water) does not influence the solvent capacity for an other compound to be accomodated. It may happen that the presence of A aids the solution of B in your solvent, increasing the solvent capacity for B. Conversely, the presence of A may lower the solvent capacity for B, too -- the experiment will tell you the ultimate truth.
