Accessing AWS SQS running under different AWS root account

Background: My application reads from a AWS SQS queue. I have all my AWS Resources under one AWS account [not IAM user accounts but main AWS root account].

Question: I have to access the SQS queue which is created under an AWS account that is different from account for all my AWS resources. My question is will this work. I only have one account to experiment with and cannot test the scenario my self.

Any help is appreciated.

Cheers.
