Optionally:

for x in mylist:
    if len(x) >= 4:
        sku.append(x[4])

But do you really need to save the whole file in a list first?
You could simply do:

for record in csvreader:
  if len(record) >= 4:
      sku.append(record[4])

Or even:

sku = [record[4] for record in csvreader if len(record) >= 4]
