IMO its better to give kittens the kitten food for awhile. Many kittens have survived eating adult foods, but the kitten is made specifically with higher nutrition for growing bodies.
Adult cats (spayed/neutered) shouldn't be eating kitten food because it will put on weight too fast.
Most people feed kitten food till around a year, but I believe it depends on the type and size and activity of the kitten as to how long you should feed them. With smaller built cats (rexes, siamese, orientals, etc.) you don't want them on kitten food for a long time - they WILL get fat quickly. My rex kittens were only fed kitten food for the first 4 months of age - after that they got adult food and were fine show cats
Charlie was on kitten food till about 5 months old - then adult food and he's very solid - 7 months old and a little over 8 lbs.
Cats such as maine coons, ragdolls and other cats that are 15+ lbs when grown would do better to eat kitten food till almost a year old.
