Cook became just the 12th player in history to score 10,000 Test runs during the course of his unbeaten 47 as England beat Sri Lanka by nine wickets in the second Test at the Riverside in Chester-le-Street yesterday.
The England captain was also the first Englishman to achieve the feat and, at 31 years and 157 days, the youngest to get to the landmark, breaking Tendulkar's record by more than five months.
Cook is unlikely ever to play white ball international cricket again having been dropped from the one-day side prior to last year's 50-over World Cup.
However, given Cook has scored at a rate of around 1,000 runs a year for the past decade, only a career-ending injury or a sharp decline in form could deny him the chance to surpass Tendulkar's haul.
"It will be about how long he wants to keep doing it," said Bayliss.
"But certainly there is time on his side, so there is no reason he couldn't if his heart is still in it and his will to do it is still there," the Australian added.
"He is not the biggest stroke-player of all time - (but) he knows his game very well, he is very patient and he sticks to it. To be able to do that over period of time he has played and score as many runs as he has is a fantastic effort."
Victory at the Riverside, the headquarters of north-east county Durham, saw England take an unassailable 2-0 lead in their three-Test series with Sri Lanka.
Fast bowler Steven Finn, who plays at Lord's for Middlesex, could be vulnerable if England want to assess Ball in international match conditions ahead of their upcoming home Test series against Pakistan.
But Bayliss indicated Finn and struggling number three batsman Nick Compton, another Middlesex man, would get a fair run to prove their worth.
"There have been discussions over the last month or so, but we have been about giving guys the opportunity to show us what they have got," said Bayliss.
