http://animals.howstuffworks.com/mammals/anteater-vs-a... They have a lot of difference between each others. Mostly the anteaters have claws while aardvarks have simil-hooves. The snout of a aardvaark is more pronounced and looks more similar to a pig, while the anteater's one ends in a curvier and pointer way. Aardvarks also have a different mouth structure (mostly they have teeth, while anteater don't). Most importantly, the anteater have a lot of fur and fluffy tails (at least the one Bonnie is based on) while aardvarks have really short fur and stubby tails. Aardvarks have way more pronounced ears than antearers, So i can understand why people might think she's one. But Bonnie is based more on the cartoon-styled anteaters rather than the actual animal.
