You could as a creative metaphor, but it would be unusual and potentially confusing. Words like 'obstacle', 'hindrance', 'bottleneck', or 'drag' are more natural in everyday language.

In chemistry, they are often synonymous. However, 'inhibitor' is a broader term, while 'anticatalyst' specifically implies acting against a catalyst. 'Anticatalyst' is less frequently used.
