This is not recommended. 

Choose one eBay category to map your product to. In some cases you may get charged for listing 1 product in multiple categories.

Note: From 4 April 2018, when you list an item in two or more eBay categories and there is a difference in final value fees between the categories, the highest final value fee will apply when your item sells.

eBay strongly encourage you to list your item in the single most relevant category rather than multiple categories. 

This will ensure that the most accurate and helpful search results are returned in buyers’ searches.
