I'm not aware of any idioms, but how about a simple function?
def listinlist(list1, list2):
"checks if list1 is in list2"
if not list1:
return True
if not list2:
return False
length = len(list1)
pos = 0
while True:
try:
pos = list2.index(list1[0], pos)
except ValueError:
return False
if list2[pos:pos+length] == list1:
return True
pos += 1
