"He's met the manager, there's been discussions, but that doesn't mean the deal is done," he told BBC Radio Stoke.
"With transfers these days it's not cut and dried with one conversation - that's where we're at with this one."
Kemp also revealed that he does not expect
Senegal striker Demba Ba to join the club
from German outfit Hoffenheim.
The 25-year-old had agreed personal terms with the Potters and was set to sign for about £6m but failed a medical last week.
This does not sit with Pulis' recent edict that he is looking to reduce the overall age of the squad
"He's not fit to play right now and we want players that can play right now, come in and make an impression, and I don't think he's in a position to do that," said Kemp.
"That's not to say the deal couldn't be resurrected some time in the future, but I don't think it will be done in the foreseeable future."
Carew is out of contract at Villa Park at the end of the season, and his future under manager Gerard Houllier is in doubt following the arrival of
record signing Darren Bent on Tuesday.
Carew joined Villa from Lyon in 2007, and was a key member of their side under former manager Martin O'Neill.
But injury has prevented him from making an impact this season, while his relationship with Houllier has been strained, with the pair exchanging words in the press last year.
Carew called the Frenchman disrespectful after the striker was challenged to earn a new contract, with Houllier responding by calling the former Valencia man "stupid" and telling him to stop "living in the past".
Birmingham and West Brom have been linked with Carew, with Baggies assistant manager Eddie Newton last week declaring his club's interest.
Despite falling out of favour under Houllier, Carew was a surprise starter in the Midlands derby with Birmingham last weekend.
