Does 3 years of science hurt my chances of getting in?

This thread is a variation of a theme, so I am closing as duplicative. Users can comment on the earlier thread:

Does computer science count as a science?

I want to take computer science this year (my senior year of high school), but the only way I’d have room in my schedule is if I drop my other science electives (environmental and forensics). For college admissions, I know most schools prefer 4 years of science and I don’t want to do anything to reduce my chances of getting into competitive schools. Will colleges see computer science as a way to fulfill their 4-year science standard? If it depends on the school, I’m applying to Creighton, Boston College, and my state flagship.
