I was told you can't paint a vinyl exterior of a house. Is this true?

From Exterior Painting Tips Looks like you can.

"Aluminum and vinyl siding present special challenges when painted. Aluminum siding frequently suffers from excessive chalking and may contain dents and imperfections. Pressure wash or hand-scrub to remove chalk and rinse afterwards. Satin or low lustre paint is the best choice for aluminum siding because it hides dents and makes the imperfections less noticeable. A spray application gives the best appearance. Vinyl siding has the same problems with one additional limitation. Vinyl siding has a tendency to buckle or warp irreversibly from hot, direct sunlight. Darker colors will absorb more heat, so select a paint color no darker than the original color of the original vinyl."

I know Sherwin Williams makes a specific paint to go over vinyl siding. Good Luck!

I was in the business of paints and coatings manufacturing for many years as as paint formulator. This question comes up often. Michaelb correctly answered your question, ( surface preparation is very important), but he left out what type of paint to use. After years of testing, the conclusion is to simply use a good quality Acrylic Latex House Paint. Good Luck!

All great answers above!
