Yes. And it's common courtesy for most of the big bands. Not to be mistaken with saying that they aren't playing live because they most certainly do. But it's much more smoke and mirrors than many may think. They do have pre-recorded tracks for choruses and certain lead singer vocal lines in there at a certain (lower) volume to give it more power live. When Nickelback played in Cologne a few years agp, they spontaneously entered a jam session and Chad was standing on the side of the stage talking to somebody while his vocals were still very audible coming over the PA.

With Bon Jovi, it's been nothing else: On the New Jersey tour, Jon faked that high "Livin' On A Prayer" before the solo throughout and once, in Chile, they forgot to trigger the backing track. Just look at Jon's stink eye towards the sound mixer at 4:20

On the KTF tour, they had certain back-up tracks as well. I'm sure the chorus of Keep The Faith had some of it, the "faith" parts were triggered by David Bryan if I remember correctly as well. Take In These Arms from Dortmund 1993 at 1:56:48
After Jon had improvised, he puts his mic down and you can CLEARY hear his "baaabyyyy" over the PA.

In 2013, when he had his hayfever attack in Sofia, people mentioned that you could still hear his voice at parts like ITA while David was actually singing for Jon.

As I said, this doesn't take anything away from Bon Jovi's outstanding playing for three decades! All of the bigger acts do have that and I think it was either Jon or Richie who once said that "live shows are always a bit of mirrors and smoke". When I first saw Bounce, they just played live as 5 guys and some of the stuff sounded somewhat empty. Until they got that advice from the person who had worked in the business (mentioned above) and added a few pre-recorded tracks to (especially newer) songs and went into their studio to record gang vocals for some choruses like It's My Life. Since then, the sound has gotten much fuller and powerful.
