In theory, there is nothing to prevent someone from obtaining more than one renter's policy to cover the same property and liability exposures but should a claim occur most policies have language requiring you to declare other insurance that may cover your claim. Failing to declare the existence of other insurance may void your coverage entirely.
If other insurance is available, the policy will outline how the claim would be addressed. In some situations, like property coverage, each company would "share" the loss. In others, each insurer may share the loss or one policy would be considered "excess" of the other and payment would be made only when one policy's limit is exhausted.
You may also find questions concerning "other insurance" on the application you complete and sign when purchasing insurance. Many companies may shy away from writing coverage when they know duplicate coverage exists.
Generally, I would say it is not a good idea to have two renters policies covering the same insured.
