Entire article about eating apple cores.
Here's the article they linked about eating article cores:

It basically says that one core isn't a problem, but that conceivably, a crazy toddler (said with love, they're all crazy) who ate a ton of seeds could get sick.
Given that my kid would sometimes go on a food jag and eat lots of a favorite food, and I could imagine him choosing to eat a half dozen apples in a day, I might remove the cores going forward. But I wouldn't worry about one apple.
