Yes. Put coin = random.randrange(2) inside the while loop.
import random
heads = 0
tails = 0
counter = 0
coin = random.randrange(2)
while (counter < 100):
if (coin == 0):
heads += 1
counter += 1
else:
tails += 1
counter += 1
coin = random.randrange(2)
print "\nThe coin landed on heads", heads, "times."
print "\nThe coin landed on tails", tails, "times."
