Unelected Mod
1. GRRM has been involved in tons of casting decisions. This means fuckall.1. gurrm being involved the selection
2. Her possibly being the same age as a Jon which would mean she was a bastard
3. Her looking like a twin to Jon.
2. Possibly being the same age, that is she is probably within a year of Jon's age. Shocking! Lots of people probably had lots of sex before and after going out on a campaign.
3. She has long brown hair like Jon but different eye color. She is short and slim, Jon is lean. That is about as much of how she looks like a twin to Jon.
So basically bullshit. No supporting evidence whatsoever.
On the other hand, we have all kinds of evidence against it. For one, she is Meera Reed, not Meera Snow. Also, while Ned thinks about having to tell Jon something, he never thinks of Meera. It also doesn't match the stuff that happens in the House of the Undying.
