  May I ask why you need such a command? What should a leading label do?

This is something I suppose could work for you:

documentclassarticle
usepackagecaption
usepackagehyperref
defmyEmptyLabel#1
newcommandremovelabel[1]letoldlabellabelletlabelmyEmptyLabel#1letlabeloldlabel % some code
begindocument
beginminipagetextwidth
removelabelcaptionoffigurelabelsome_label This label should be removed % output: 'This label should be removed'
endminipage
removelabelThis string is already label-less % output: 'This string is already label-less

Figure~refsome_label
enddocument

In the output the label is not defined and returns questionmarks

Edit:

documentclassarticle
usepackagecaption
usepackagehyperref
defmyEmptyLabel#1
newcommandremovelabel[1]letoldlabellabelletlabelmyEmptyLabelxdefremovedlabel#1letlabeloldlabel % some code
begindocument

removelabellabelsome_label This label should be removed 
removedlabel

removelabelThis string is already label-less % output: 'This string is already label-less

removedlabel


%Figure~refsome_label
enddocument

Now removedlabel gives the string without the label... But I am not sure what you want to do... May be you should be more clear on what you expect from the command.

  This code isn't actually removing the label, it just briefly changes the behaviour of the label command to null. If I were to print the argument of removelabel as if it was a string, I'd still see labelsome_label.

  @koleygr label shall not deliver visible things into the output-file/pdf-file. @bsphack/@esphack ensures that a space-token behind the argument of a label-command does not produce undesired visible whitespace in case there already was a space before the label-command...
