You CAN, but most people don't.
For instance, going for a big fast serve, most people lean into the court with a toss maybe a foot inside the baseline.
Then, missing that, and fear creeping from within, they toss right at the baseline to dink the second serve, but their body forgot to make the adjustment. I see that happenning all the time in lower levels of tennis. It happens to me quite often, actually, me going for a certain serve without the mechanics needed for that serve, my mechanics still lagging behind with the previous serve.
Like an up the center stripe serve missed, so you decide to go wide, but your mind forgot to tell your body somehow, and you hit off balance.
Substitute the "you" for ME... Had a discombobulated day today.
