Yep- 'disordered' eating can cover a range of habits that would be considered abnormal whether that's severe restriction, a binge-purge cycle, obsession with only eating 'healthily' or avoiding certain foods, a mix of those behaviours or something else (known as EDNOS which doesn't fit one specific eating disorder category). You also don't have to be severely underweight to have an eating disorder, they can happen at any weight and some eating disorders don't necessarily result in weight loss (but do result in other damage such as the effects of repeated vomiting or malnourishment by limiting the range of food eaten)
