Technically? That's what splinching is; if you're not entirely focussed on the apparition proper you could end up leaving a part of yourself behind and hurting yourself. Of course the Healers can generally put you back together again but it's very painful and... Not recommended. At all.

[ Thankfully, Hermione has always been rather good at apparition. She relied on it during their year travelling around England, even though she almost lost Ron in the process once. She still hasn't quite forgiven herself for that and she does her best not to think about it now, shaking her head and, of course, focusing on what Luke is saying to her.

... Even with the ridiculous teasing. Honestly. ]

It - Isn't that some kind of muggle pickup line? Really, Luke?
