你好,同学,很高兴回答你的问题

正确答案：不可以.

（一）、when,while都有“当……时候”的意思.when既可表示某一点时间,也可以表示某一段时间 .在when引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的,可与主句中的谓语动词同时发生,也可在其后发生. 例如：

1、I was just reading a book when she came into my room.

她走进我房间时,我正在看书.

2、Were you writing when the teacher came in?

老师进来的时候,你在写信吗?

3、When he was a child he was always trying out new ideas.

他小时候就常常试验一些新的设想.

（二）、while只能表示某一段时间,不能表示某一点时间.在while引导的时间状语从句中,其谓语动词只能是延续性的,而且也只能与主句中的谓语动词同时发生或存在. 例如：

1、While Jim was mending his bike, Lin Tao came to see him.

正当吉姆修自行车时,林涛来看他.

2、You can’t do your homework while you’re watching TV.

你不能一边看电视一边做家庭作业.

（三）、另外,when和while的区别还在于：while引导的时间状语从句多用进行时态,而when引导的时间状语从句多用一般时态. 例如：

1、While they were talking , the bell rang.

正在他们谈话的时候,上课铃响了.

2、I was doing my homework when my mother came back home yesterday evening.

昨天晚上妈妈回家的时候,我正在做家庭作业.

第（一）（二）和第（三）条能解释你这道题,在when引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的,可与主句中的谓语动词同时发生,也可在其后发生.在while引导的时间状语从句中,其谓语动词只能是延续性的,而且也只能与主句中的谓语动词同时发生或存在.打电话的动作不是延续性的,而且不可能和逛商店同时进行；while后面一般用进行时态,when后面多用一般时态.

另外,麻烦你把本题的分类修改到外语学习分类,谢谢合作.
