Yes. BOS does not prevent a survey from being completed many times on the same computer or from the same IP address.
If you wish to restrict your survey so that only certain people can complete it, you can set this up yourself using survey access control. You can set up an overall survey password, so that only people who possess the password can complete the survey, or you can set up a list of respondents, so that only certain respondents can complete the survey and each respondent can only complete it once.
In both cases (password and respondent list), there is still no restriction on how many times a single computer can be used to complete the survey.
